In the past decade, inverter testing has become a very important and complex issue during inverter developments. State-of-theart inverters, key components of electrical power trains, offer multiple functions, high reliability, fault tolerance and they must ensure a high level of functional safety. Especially automotive applications prove to be demanding due to their exceptionally high dynamic requirements, challenging mission profiles, harsh environment and special test cases such as the “curb stone edge” case with high currents, high dynamic and no speed. Conventional test methods such as motor test beds or active / passive RL-loads are not suitable to verify inverter functionalities in a sufficient manner. This paper presents a new and powerful inverter testing technology: The EMotor Emulator – testing power electronics without an e-machine.
