Design and Implementation of Power Converters to Emulate Motor Regeneration Power

This paper presents design and implementation of power converters to emulate motor regeneration power. A new electric motor emulator (EME) model is proposed to simulate the transient phenomenon of a motor under braking. The motor is a device that converts electrical energy through magnetic energy into mechanical energy, and its response time is much slower than that of electrical power conversion. Therefore, it is possible to adopt power converters to emulate motor operation, which can be used to test a designed motor driver and can recover the driving power back to the AC grid during regular operation. In particular, this paper also presents an approach to emulating the transient behavior of a permanent magnet synchronous motor (PMSM) under braking. Simulated and experimental results are presented to verify the feasibility of the discussed design and implementation.
