Agenda:
The two most challenging Hardware in the Loop (HIL) testing applications in the Electric Vehicle (EV) domain are motor drives and battery chargers. Developing and testing control software for these power converters are challenging due to: high switching frequency, new wide-bandgap semiconductors, highly nonlinear motors, new topologies, and their safety critical role.
To enable comprehensive HIL testing of EV power electronics controllers under all the operating conditions, including faults, it is necessary to use high-fidelity plant models able to capture all the relevant real-world phenomena. These include semiconductor power losses (including switching and conduction losses), on-state voltage drops and switching delays, heat-sink thermal models, motor nonlinearities including spatial harmonics, inter-winding short circuits etc.
