Enhanced Power Electronics System for High-Performance Testing of Motor Control Units in a Power HIL Environment

Inhalt:
Hardware-in-the-loop (HIL) simulation is an established test method for analyzing motor control units (MCUs). For highly integrated drive controllers, the controller and the power electronics must be tested at the electric power level (emulation). Using this method requires specific power electronics for emulation. This paper introduces a special hardware solution that is based on an interleaved switching, three-level neutral-point-clamped (NPC) inverter and a sophisticated model-predictive control algorithm to establish a high-bandwidth electronic load for testing electronic power systems.
