Abstracts:  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 firstly 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 about 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.

Biography:  Prof. Fei Gao is currently the Deputy Director of the French national CNRS research institute FEMTO-ST and a Full Professor at the School of Energy and Computer science of UTBM, where he was an Associate Professor between 2011 and 2017. He 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. 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. He is nominated in 2017 as Conferences Committee Chair of IEEE Transportation Electrification Community. He serves since 2019 as Secretary of the Technical Committee on Vehicle and Transportation Systems of IEEE Power Electronics Society and was Chair of the Technical Committee on Transportation Electrification of the IEEE Industry Electronic Society between 2018-2019.
