Leaping the Gender Gap! Why Engineering is a Worthwhile Career

Leaping the Gender Gap! Why Engineering is a Worthwhile Career

I have been working as an engineer for more than 40 years. The job is very interesting and worthwhile
for me, because equipment which I studied, developed, and verified is used in society, and contributes to
people's lives. Engineering is a profession to enrich people’s lives by solving technical issues and
launching products into society. The evaluation is given to the result of "technology". In that sense,
engineering is one of the professions where gender has the least influence on evaluations.
In my presentation, through my experience, I would like to explain the rewards as an engineer regardless
of gender.

A Futuristic Medium-Voltage Grid-Connected Multi-Port Public Electric-Vehicle Ultra-Fast Charging-Station with G2V and V2G capability

A Futuristic Medium-Voltage Grid-Connected Multi-Port Public Electric-Vehicle Ultra-Fast Charging-Station with G2V and V2G capability

Medium-voltage (MV) grid-connected solid-state-transformer (SST) based fast-charging (FC)  stations provide several merits in terms of improved efficiency, power density, current limiting capability, etc. However, the propositions in literature are either not bidirectional (to simultaneously support V2G and G2V) or are unable to interface multiple types of plug-in electric-vehicles (PEVs), which are not able to meet the expectations of future fast-charging infrastructures. The fast-charging solutions available commercially are mostly for interfacing with the low voltage grid, and are unable to connect multiple type of PEVs. In this lecture, a futuristic  MV grid-connected public multi-port FC/dC station is presented which not only resembles a conventional vehicle refuelling station’s functionality by simultaneously interfacing all three types of PEV categories (heavy or hPEVs, medium or mPEVs and light or lPEVs), but also facilitates bidirectional power flow for V2G applications. The modulation, operation and control schemes of the front-end (FE) MVAC-LVDC single-stage conversion and back-end (BE) DC-DC conversion of the proposed architecture are presented in details. Real-time digital-simulator (RTDS) based  Hardware-in-loop (HIL) test results for full-scale 22 kV, 1 MVA architecture’s bidirectional operation verifies the proposed operation and controller for full-scale operation. The architecture facilitates simultaneous FC/dC of 1 hPEV within 49.5 min, 2 mPEVs within 28 min and 4 lPEVs within 16 min, while adhering closely to the prescribed charging/discharging schedules of each  PEV. Finally, a proportionally scaled down 1 kV, 13.2 kVA experimental verification validates the architecture’s performance during drastic net power flow change conditions and exhibits a peak efficiency of 96.4% with a power density of 3.2 kVA/L. A comprehensive benchmarking of the proposed architecture with commercially available FC products is also presented.

A Plug and Play Operational Approach for Implementation of an Autonomous-Micro-Grid System

A Plug and Play Operational Approach for Implementation of an Autonomous-Micro-Grid System

The electric power system is going through an unprecedented transformation and related challenges in the implementation of smart grids. The smart grid is based on the flexible electrical power system that coordinates different energy resources and loads with the aim of delivering sustainable, economical and reliable electrical supply to the loads in an efficient manner. In this presentation, a plug and play type autonomous-microgrid system formation is proposed. Multiple distributed generating sources and loads interaction is considered pertaining to the stability of the micro-grid. The proposed method enables communication-less operation of each of the elements of the micro-grid system. It is also considered that the sources are of different power capacity as can be seen in a typical autonomous micro-grid system. Spatial Repetitive Controller (SRC) is proposed to control each of the distributed generating sources in a decentralized manner to stabilize the overall micro-grid system. The proposed system considers sudden change in load as well as other distributed generators conditions like a true plug and play operation. A novel signature frequency voltage injection method is proposed to identify the presence of special distributed generator and operation of backup distributed generators. The implemented control architecture also ensures stability of the micro-grid fundamental frequency even in the case of dynamic conditions unlike the traditional droop-control method. A detailed experimental study is carried out and the experimental results presented show the efficacy of the proposed system.

Design Optimization Framework for Solid-State-Transformers: A Novel Approach for an Emerging Technology

Design Optimization Framework for Solid-State-Transformers: A Novel Approach for an Emerging Technology

The power electronics technology is expected to dominate the power systems of the future due to the necessity of continuous controllability of power flow and enhanced smart functionalities. A focussed review of the medium-voltage (MV) grid-connected isolated power conversion techniques, regarding their relevance and applicability for bidirectional medium-voltage AC – low-voltage DC (MVAC-LVDC) conversion, reveals the need for high-power density power architectures with comparable efficiency and cost with respect to contemporary line-frequency transformer (LFT) based solutions. Some of the emerging applications of such bidirectional MVAC-LVDC converters are in electric-vehicle (EV) charging, Energy Control Centre (ECC) for microgrids, Green Data-Centre power distribution, etc.

Due to the lack of a comprehensive multi-objective optimal design framework for isolated MVAC-LVDC conversion, MVAC-LVDC converter designs are mostly obtained through trial/experience. The challenges of computationally expensive magnetics design, coupled with the correlation between magnetics design and performance of semiconductor devices, may be effectively tackled by developing hybrid (numerical+analytical) local optimization algorithms. This local optimization could be subsequently learned through machine-learning techniques, using a limited number of optimal design datasets, and, thus, assists in the genesis of globally optimal design limits for several combinations of semiconductor devices and switching frequencies. The commercial SiC-MOSFET based MVAC-LVDC isolated converter designs not only provide 10-12 times better power density compared to LFT based solutions, but are also observed to offer better efficiency-power density optimal designs compared to Si-based designs by providing a power density improvement of 3-4 times for comparable efficiency performance.

Single-phase inverter control techniques for interfacing renewable energy sources with micro-grid – Parallel connected inverter topologies with active and reactive power flow control along with grid current shaping

Single-phase inverter control techniques for interfacing renewable energy sources with micro-grid – Parallel connected inverter topologies with active and reactive power flow control along with grid current shaping

Renewable energy sources (RESs) have been receiving significant attention recently worldwide as a sustainable alternative type of energy supply in the energy mix. Inverters are being used to convert the dc voltage into ac voltage before being injected into the grid or isolated loads.

In this presentation, a novel current control technique is proposed to control both active and reactive power flow from a renewable energy source feeding a micro-grid system through a single-phase parallel connected inverter. The parallel connected inverter ensures active and reactive power flow from the grid with low current THD even in the presence of non-linear load. A p-q theory-based approach is used to find the reference current of the parallel connected converter to ensure desired operating conditions at the grid terminal. The proposed current controller is simple to implement and gives superior performance over the conventional current controllers such as rotating frame PI controller or stationary frame Proportional Resonant (PR) controller. The stability of the proposed controller is ensured by direct Lyapunov method. A new technique based on the Spatial Repetitive Controller (SRC) is also proposed to improve the performance of the current controller by estimating the grid and other periodic disturbances. Detailed experimental results are presented to show the efficacy of the proposed current control scheme along with the proposed non-linear controller to control the active and reactive power flow in a single-phase micro-grid under different operating conditions.

Single-phase inverter control techniques for interfacing renewable energy sources with micro-grid: Series connected inverter topologies with active and reactive power flow control along with grid current shaping

Renewable energy sources (RESs) have been receiving significant attention recently worldwide as a sustainable alternative type of energy supply in the energy mix. Inverters are being used to convert the dc voltage into ac voltage before being injected into the grid or isolated loads.

In this presentation, a control strategy for a single-phase series connected inverter with the micro-grid is proposed to interface AC loads not only to regulate the load voltage under voltage disturbances but also, to control the load power drawn from the micro-grid. The inverter compensating voltage works in such a way that, irrespective of any type of disturbances in the micro-grid voltage (such as sag, swell or harmonic distortions), the load voltage is maintained at its rated voltage level with low THD in voltage. The proposed control strategy also facilitates a specific amount of active power flow (from renewable energy source) to the load irrespective of the micro-grid voltage condition. The rest of the load power is supplied by the micro-grid. To facilitate this control strategy a Spatial Repetitive Controller (SRC) is proposed and implemented in micro-grid phase (q ) domain to make the controller independent of the micro-grid frequency. The proposed controller ensures dynamic stability of the system even if there is a sudden change in the micro-grid frequency. Detailed experimental results are presented to show the efficacy of the proposed series inverter system along with the controller under different operating conditions

Improved Control Algorithm for Power Quality Controlled Converters

Improved Control Algorithm for Power Quality Controlled Converters

This presentation covers control algorithms for active filter (AF). A three-phase insulated gate bipolar transistor (IGBT) based current controlled voltage source inverter (CC-VSI) with a DC bus capacitor can be used as an AF. There are many control algorithms for the AF such as reactive power control, active power control, power-balance control, direct and quadrature (d-q) model-based control systems, etc. It is noted that most existing feedforward control methods of the AF system result in switching notches (sharp-rising ripples) in the supply current during transitions of the stepped waveshape nonlinear load current. Through laboratory experimentation, it is demonstrated that the direct current control method, which works on the principle of feedback, eliminates switching notches in supply currents and locks sinusoidally shaped three-phase supply currents in-phase with the supply voltages. Use of wide bandgap (WBG) devices will also be discussed as WBG devices offer significant potential to miniaturize AF hardware.

Breaking the Barrier of Bulky Magnetics in Power Conversion: Advances in Resonant Switched-Capacitor Converters

Breaking the Barrier of Bulky Magnetics in Power Conversion: Advances in Resonant Switched-Capacitor Converters

PWM converters have been the working horses for most power conversion applications to date. Thanks to topology and material evolution, their power density has been increasing over the years. However, bulky magnetic components remain a significant challenge. Researchers in the field have been continuously searching for new power converters with similar regulation capabilities but much higher power density. The UCI Power Electronics Laboratory has dedicated its efforts to this search at the confluence of PWM, resonant, and switching-capacitor converters for the past eight years. During this journey, several new switched-capacitor converters and resonant switched-capacitor converters were discovered. Recently, the laboratory made a breakthrough by realizing full-range voltage regulation of resonant switched-capacitor. In this speech, Dr. Smedley will present general "PWM-like" resonant switched-capacitor converters capable of full voltage regulation within a narrow 2X frequency swing. This new generation of power converters can operate at much higher switching frequencies compared to their PWM counterparts, with natural soft-switching using only one small inductor (not for energy transfer, no DC bias). As a result, bulky magnetics can eventually be eliminated in fully integrated power chips, providing a solution for high power density applications in the future. Moreover, this new PWM-like operation is applicable to most known switching capacitor converters, enabling topological manipulation to achieve functions such as step up, step down, inverse polarity, AC/DC, and DC/AC.  These converters can replace a wide range of conventional PWM converters.

Exploration at the Confluence of Three Major Power Electronics Branches

Exploration at the Confluence of Three Major Power Electronics Branches

High-frequency power electronics progresses along three major branches: PWM converters, switched-capacitor converters, and resonant converters. PWM converters have been the workhorse for most power conversion applications today. However, their bulky magnetics limit further power density improvement. Switched-capacitor converters do not need magnetics, but poor voltage regulation prevents them from a wide adoption. Resonant converters have penetrated some applications, but they are not ready to replace the PWM converters for high-power applications due to their high RMS voltage/current.
Researchers in the community have searched for new solutions with better efficiency, regulation, and power density. As a result, there has been increased intertwining and interactions among these branches.
The UCI Power Electronics Laboratory has been working at the confluence of PWM, resonant, and switched-capacitor converters for >7 years. During this time, we have invented several new switched-capacitor converters and resonant switched-capacitor converters. Recently, we made a breakthrough in a general “PWM-like” control/modulation method applicable to most resonant switched-capacitor converters to achieve full range voltage regulation with only a 2X frequency swing and only one small inductor (nano-henry scale without DC bias). This new generation of power converters has the potential to replace a wide array of conventional PWM converters and dramatically reduce magnetic components or eliminate the bulky magnetics overall in fully-integrated power-chips.
This lecture reports our discoveries at the confluence of these major power electronics branches.

One-Cycle Control and Its Application for Stabilizing Power Grids with High Renewable Penetration

One-Cycle Control and Its Application for Stabilizing Power Grids with High Renewable Penetration

One-Cycle Control (OCC) is a nonlinear control technique for switching converters.  It achieves pulse-width modulation (PWM) by comparing the average value of a switched variable to a reference to ensure equality in each switching cycle.  OCC enables precise control of a converter's dynamics in one switching cycle, making it suitable for solving complex control equations.  Precision, speed, universality, and simplicity are the most notable features of OCC.  In fact, OCC is by far the fastest control reported for power converters.

One worth-noting example of OCC is its ability to realize four-quadrant universal control of three-phase inverters, which allows an inverter to perform power factor correction (PFC) rectification, inverting, dynamic VAR compensation (DVC), active power filtering (APF), or any combination of these functions.  Using OCC, these complex control tasks can be achieved with a simple control circuit, offering ultrafast and powerful power conversion for modern grids, electric vehicles, more electric aircraft, and other areas of applications.

In this presentation, Dr. Smedley will explore the application of the OCC dynamic VAR compensator (DVC) to address the increasing instability of power grids in high renewable penetration scenarios. The present power grid is already under significant stress due to lagging infrastructure updates in response to the growing demand for electricity. This issue is compounded by the intermittent and rapid transients of renewable energy sources. For instance, in circuits with a decent amount of solar penetration (even 10-15%), voltage changes can occur rapidly due to passing clouds, causing systems to switch on and off frequently. The traditional grid equipment for voltage regulation will wear out much more quickly, making the adoption of renewables an expensive prospect.  VAR compensation is a well-established Flexible AC Transmission System (FACTS) method for stabilizing voltage. However, to handle the rapid transients of renewable energy, much faster speed is required. The OCC method has demonstrated exceptional VAR speed for mitigating the impact of intermittency in renewable energy output and other disturbances. OCC-DVC provides a solution to enhance the grid's flexibility and resilience.

Advanced Bi-directional DC-DC Converters in Battery Energy Storage Systems

Advanced Bi-directional DC-DC Converters in Battery Energy Storage Systems

Battery energy storage systems (BESS) are the main infrastructures in the microgrids to ensure power balance and stable operation, as well as in the utility grid to enhance flexibility and stability. Bi-directional DC-DC converters are the key elements in BESS, which interface batteries and DC bus for power transfer. In this lecture, a comprehensive review for isolated bi-directional DC-DC converters is presented. The requirements of BESS on isolated bidirectional DC-DC converters with high efficiency and high power density are introduced. Two major solutions of isolated bidirectional DC-DC converters, CLLC resonance converter and dual-active-bridge (DAB) converter, are investigated and compared, including modeling methods, control strategies and design considerations with the use of SiC and GaN devices. This lecture points out that both CLLC and DAB converters have their own advantages and good application prospects in future large-scale energy storage systems. Moreover, a modular multi-port CLLC converter based on high frequency AC bus sharing is proposed to integrate multiple battery stacks, which features high efficiency, high reliability and good scalability.

Hybrid AC/DC Microgrids: Configuration, Control and Future Development

Hybrid AC/DC Microgrids: Configuration, Control and Future Development

Hybrid AC/DC microgrids with DC and AC sources/loads are considered to be the most likely future microgrid structures, since DC subgrid features high efficiency and free of harmonics/reactive power, and AC subgrid is easy to connect conventional utility grid. A panoramic overview of hybrid AC/DC microgrids is given in this lecture through the review of ongoing projects. The operation control and power management strategies of hybrid AC/DC microgrids based on the inter support between AC subgrid and DC subgrid are discussed. High penetration integration of renewable generation brings some challenges into hybrid AC/DC microgrids, hence, this lecture focuses on the coordination control between renewable generation and energy storage.

Moreover, as a future trend, the conceptual framework of networked microgrid clusters is introduced to further enhance system operation flexibility. Smart multi-functional services of AC/DC interfacing converters are presented in terms of resilience control, active stabilization, power quality improvement and cost-efficiency optimization.

Recent Developments in Wireless Power Transfer Systems for Ventricular Assist Devices/Artificial Hearts

Recent Development in Wireless Power Transfer Systems for Ventricular Assist Devices/Artificial Hearts

The number of patients with serious heart failure has been steadily increasing. Therapies
based on Ventricular Assist Device Systems (VAD) and Artificial Hearts (AH) are considered
as standard treatment options for patients with severe heart failure. The potential of serious
infections associated with the percutaneous driveline is a major issue with the current VADs
and AHs. Wireless Power Transfer Systems (WPTS) are proposed as a potential solution to
eliminate the through-skin driveline. In this lecture, new coil structures and control methods
for WPTS based VADs and AHs are presented.

Degradation Conscious Optimal Control of Li-ion Batteries

Degradation Conscious Optimal Control of Li-ion Batteries

Li-ion battery cells tend to degrade due to aging or cycling. One main cause of the degradation
is the formation of solid electrolyte interface (SEI). The formation of SEI causes reduction in
Li-ions availability, increase in the internal resistance and self-discharge of cells. More
advanced battery management systems (ABMS) use mathematical cell models for state
estimation and control strategy design. This lecture discusses recent developments in ABMSs,
that minimize the cell degradation and energy losses in the interfacing converter, leading to a
reduction in the rate of capacity loss in the battery pack and the maximum battery pack
utilization.

Accurate Core Loss and Winding Loss Characterisation and Prediction for High-frequency Magnetic Components

Accurate Core Loss and Winding Loss Characterisation and Prediction for High-frequency Magnetic Components

Power loss modelling of magnetic components becomes increasingly important in the design of power electronics converters, especially in the case of higher switching frequencies enabled by emerging wide-bandgap devices where the magnetic component loss can be significant. There are clear challenges in both the core loss and winding loss estimation. For the core loss, under PWM (rectangular) excitation with dc-bias and non-50% duty cycle, the conventional Steinmetz Equation or Improved Steinmetz Equation are not accurate anymore. For winding (copper) loss, the increased skin and proximity effect and random winding patterns make the conventional modelling methods very difficult to work. This lecture will introduce a ‘Triple Pulse Test’ (TPT) method, which can be used to predict the losses of magnetic components through a number of tests with three pulses and a loss map. The proposed TPT is analogous to the common ‘Double Pulse Test’ for characterising the losses of power electronics devices and converters. How to further build a user-friendly datasheet for magnetic components based on the TPT will be discussed. Several examples of inductors, transformers with various magnetic material will be given to demonstrate the proposed method.

Capacitor Voltage Control in Neutral Point Clamped (NPC) and Hybrid Multilevel Converters: Where are we now?

Capacitor Voltage Control in Neutral Point Clamped (NPC) and Hybrid Multilevel Converters: Where are we now?

The controllability of capacitor voltages in multilevel converters is essential to enable their use in practice. This includes the voltage control of the dc-link capacitors and the flying capacitors (FC). When the number of voltage levels of NPC converters is four or higher, or simplified multilevel topologies with reduced number of devices are used, the capacitor voltage control becomes particularly challenging. This lecture will introduce a new ‘Redundant Level Modulation’, when combined with optimal zero-sequence injection, has superior capability to balance the dc-link capacitor voltages and control the flying capacitor voltages through software, without the need of additional hardware. This enables conventional NPC converters with four or higher number of levels or simplified topologies to operate independently as a single rectifier or inverter (or with a passive front end) over the full power factor and modulation index range. This lecture will also review various multilevel topologies and existing control methods to introduce the new advanced modulation method. Several exemplar multilevel converters using the proposed method and how new wide-band gap devices can further facilitate the adoption of the proposed method will be shown.

Medium-Voltage High-Power Converters for 10MW+ Wind Turbines

Medium-Voltage High-Power Converters for 10MW+ Wind Turbines

The power rating of large off-shore wind turbines is getting higher and higher, reaching 14MW. Medium-voltage power conversion is generally favoured for large wind turbines in terms of higher power density, reduced current level, associated losses, cable twisting, etc. This lecture will first review existing power conversion (drive train) solutions for large wind turbines and then propose three multi-level modular high power converter topologies together with corresponding generator configurations for large wind turbines. A configuration with a 10-kV generator, a modular power converter, and a multi-winding step-up transformer will be presented in detail with experimental results, which has clear application potential for 10MW+ wind turbines. The proposed converter has fault-tolerant capability, which is essential given the high maintenance/repair cost for wind power applications. The lecture will also talk about how to reduce the amount of capacitance required in the system given the capacitors have the highest failure rates among the converter components. Furthermore, converter topology options for future 20MW wind turbines will also be presented and discussed.

Opportunities, Challenges and Potential Solutions in the Application of Silicon-Carbide (SiC) Power Devices, Converters and Motor Drives

Opportunities, Challenges and Potential Solutions in the Application of Silicon-Carbide (SiC) Power Devices, Converters and Motor Drives

This lecture will first provide an overview of the performance of state-of-the-art SiC devices and converters. While the opportunities in achieving higher-density, higher-efficiency and higher-frequency are clear, there are also significant design challenges relating to high speed (dv/dt), high voltage and high temperature operation. For example, in SiC motor drives, the high switching speed and high switching frequency can cause increased level of motor over-voltage, insulation and bearing degradation. These challenges will be analysed and several solutions aiming to fully exploit the superior characteristics of SiC devices will be given, through new topologies, new modulation and control, soft-switching, filtering, etc. Several design examples such as a 500kW high-density power converter based on SiC MOSFETs, high temperature converters with 180°C SiC BJTs and high voltage 10kV SiC converters for solid state transformer applications will be given to demonstrate the opportunities, design challenges and the proposed solutions.
