Abstract: This webinar presents some of the latest research and development of hybrid and resonant switched-capacitor (SC) power converters. In the context of data center power delivery, we showcase a few high-performance hybrid SC works with superior efficiency and power density. As an example, our latest 48V-to-12V resonant SC converter achieves 99.0% peak and 97.7% full-load system efficiency, with 6000 W/in3 power density. Various facets of the hybrid converter design will be discussed, including the analysis of topological benefits, the design of gate drive circuit and magnetics, the control techniques for soft-charging and soft-switching, and the considerations of component nonidealities. Furthermore, the concept of “multiple-operating-phase” is introduced to reduce the circuit complexity of hybrid SC converters at high conversion ratios, such as 48 V to 8 V, 6 V, and directly down to point-of-load voltages.

The objective of this webinar is to show that, while more mature topologies have seen diminishing returns in the last few years, hybrid/resonant SC solutions have demonstrated great promise with rapid improvement and outstanding performance in hardware prototypes.

Abstract: Switch mode power converters (SMPCs) play the central role in energy-efficient power conversion in emerging applications, such as electric vehicles, data centres, renewable energy, industrial automation, etc. In this context, selection of suitable modulation and control techniques of SMPCs is very important to meet challenging requirements in terms of transient performance, efficiency, stability, line and load regulation, disturbance rejection, etc. Majority of commercial controller implementations are still based on pulse width modulation and small-signal analysis. However, increasing switching frequencies using wide band-gap devices provides the opportunity to improve dynamic performance, energy efficiency and size reduction. This talk presents large-signal based control and tuning methods in existing current and voltage mode control methods, which can significantly improve performance along with improved energy efficiency in SMPCs under fixed and variable frequency modulators. Moreover, it is important to understand existing modulation, control, and tuning methods in SMPCs, to identify practical limits using small-signal based design and to formulate control and tuning methods using large-signal based approaches to achieve performance up to the slew rate limits.

Keeping this in mind, this talk will introduce a new online course which (i) presents an overview of conventional modulation and control methods, (ii) identifies small-signal performance limits, (iii) discusses large-signal based control approaches and (iv) compares strategies for controller tuning. Comparison among tuning methods illustrate how large-signal based control tuning methods can significantly improve performance and efficiency of SMPCs followed by the need for digital and mixed-signal control implementation for future power electronics converters.

Sudip MazumderPresenter: Sudip Mazumder, University of Illinois Chicago, USA

Abstract: This webinar presentation will begin with an outline on the role of control in traditional power-electronic systems and networks and how they shape the behavior of such hybrid dynamical systems. Subsequently, an overview of the traditional power-electronic control, analysis, and modeling approaches will be provided along with brief discussions on their strengths and limitations. That leads to the future of controls in power electronics (and what should and could be done beyond traditional power-electronic control) that address existing, evolving, and future applications needs and encompassing wide variation in temporal and spatial scales? This webinar will provide some insights on how and what radically new ideas may need to be synthesized that reach far beyond historical and conventional power-electronic control needs with applications including but not limited to sustainable energy systems.

Abstract: The rise of wireless power, and the adoption of next generation wireless charging technology, is helping us all achieve the dream of a world without wires.

Today’s wireless power technologies are failing to deliver what consumers are looking for when we talk about wireless charging. The most important characteristics are the ability to be able to charge multiple devices of different kinds at the same time and at a distance. A consumer may have a laptop, a mobile phone, and a smartwatch, and they want all of them to be charged simultaneously with true spatial freedom.

Next generation technologies like AirFuel RF and Resonant, enabled by emerging research, semiconductor advances, technical standards and regulatory guidance, are finally giving consumers the experience they want and need. In this webinar, we will talk about the progress we have made and the opportunities for innovation to achieve our shared dream of a world where we can power up without plugging in.
