Solar PV Microinverters-Technology-Are they Replacing the Conventional Central Inverter?   

Register Here

Abstract: The global solar microinverter market is expected to witness a compound annual growth of 17.3% from 2019 to 2025 to reach USD 5,612 million by the year 2025¹. One of the key advantages of the microinverter is that each solar panel is monitored and optimized individually for maximum output power. Further, microinverters are not restricted to panel placement in one or two different orientation such as on a complex roof layout. Use of microinverters yield more solar electricity. With so many advantages will they replace the conventional central inverter? - come find out by attending our first Online Series brought forward by the Digital Media/Education Committee of IEEE Power Electronics Society (PELS).

Both leaders in Industry and Academia will present different perspectives of “Solar PV Microinverter” technology and discuss the state of the art. Online attendees will have a chance to ask questions via the Q&A button in GotoWebinar and also can elect to receive presentation slides.

Electric Vehicles: Can Legislation Keep up with Technology by Russell Harrison

Harrison Russell 14 resizedAbstract: Are electric vehicles an emerging technology, or a mature technology? Policy makers can't decide. Some legislators believe electric vehicles are mature product, ready to sink or swim in the free market. To others, the technology is still in its infancy and requires government assistance to survive. Join IEEE-USA's Director of Government Relations, Russell Harrison, for a discussion on the state of this debate, and how it could play out in Washington and in state houses across the country.

Bio: Russ has 25 years of experience working on behalf of professional societies, companies and trade associations in Washington, D.C. He is currently Director of Government Relations for the IEEE-USA, the American component of the world’s largest technical professional society. With nearly 180,000 individual members across the United States, IEEE-USA is the leading voice for technology professionals in the United States.

Over his 17-year career with IEEE-USA, Russ has represented IEEE members on dozens of policy issues including autonomous vehicles, digital privacy, AI, federal research funding, export control, and immigration. In addition to directly engaging with policy makers, Russ strives to build bridges between engineers and politicians. He has spoken at over 260 local, national and international events about public policy and the need for regular citizens to interact with their elected leaders.

Prior to IEEE-USA, Russ represented recycling facilities and the steel industry on Capitol Hill. He has a Master’s in Public Management from the University of Maryland and a B.A. in political science from Allegheny College. Russ is a Certified Association Executive (ASAE) and Planning Commissioner (Virginia Tech).


Real-Time Simulation Methods of Power Electronic Systems by Prof. Fei Gao- Joint Webinar with IEEE Transportation Electrification Community

Fei GaoAbstract: Real-time simulation and Hardware-in-the-Loop (HIL) techniques emerge as indispensable tools in the design, modeling, testing and validation of modern power electronic systems. Different from an offline simulation, real-time simulation depends not only on the results of logical / arithmetic calculations of the model, but also on physical time (real-time) when these results are produced. Today, high accuracy real-time simulation and HIL of modern power electronics is still a great challenge. Power electronics components models are characterized by their high switching frequency and on-off characteristics. Mathematical models that contain a number of power electronic components can lead to serious real-time simulation problems (e.g. limited simulation time step size, large memory to store circuit topology due to on-off states of power switches, etc.). Solve such mathematical models while meeting the strict time constraint requires the development of specific real-time simulation techniques.

In this presentation, a general introduction of real-time simulation and Hardware-in-the-Loop (HIL) technology is first given. State-of-art modeling approaches for power electronic switches, as well as electric network formulations of power electronic systems are then presented, and their advantages and drawbacks are discussed with commercial solution examples. The main hardware implementation platforms (CPU and FPGA) for real-time simulation models are also compared. At last, a simple example of how to implement a Floating Interleaved Boost Converter (FIBC) model in real-time simulation platform for controller Hardware-in-the-Loop (HIL) application is provided using the previously presented techniques.

Bio: Prof. Fei Gao received the Master's degree in electrical and control system engineering in 2007, and the Ph.D. degree in renewable energy with distinguished Youth Doctor Award in 2010, both from the University of Technology of Belfort-Montbeliard (UTBM), Belfort, France. He is currently a Full Professor at the School of Energy and Computer science of UTBM, where he was an Associate Professor between 2011 and 2017. Prof. Gao is the Fellow of IET and the holder of the French research expertise bonus (PEDR) by the French Ministry of Higher Education and Research. 

He is also the Editor-in-Chief (2019-2021) of IEEE Industrial Electronics Technology News, and an Associate Editor of IEEE Transactions on Industrial Electronics, IEEE Transactions on Industry Applications, IEEE Transactions on Transportation Electrification and IEEE Open Journal of Industrial Electronics Society, and the Chair of Fuel Cell System Architecture Optimization Research Axis of the national Fuel Cell Research Federation FCLAB in France. He has been Chair of the Conferences/Workshops Committee of IEEE Transportation Electrification Community since 2017 and currently serves as Chair of the Technical Committee on Transportation Electrification of the IEEE Industry Electronics Society since 2018 and serves as Secretary of the Technical Committee on Vehicle and Transportation Systems of IEEE Power Electronics Society since 2019.
