Motor emulator and control method of motor emulator

Abstract

A motor emulator is configured to receive an electrical potential signal from a motor driver. The motor emulator includes control level circuit and power level circuit. The power level circuit at least includes an inductor, and an inverter circuit configured to provide an electrical potential to an output end of the inductor. The control level circuit is configured to generate a trigger signal based on an electrical potential change at an input end of the inductor and a current value passing through the inductor to trigger an electrical potential change provided by the inverter circuit to the output end of the inductor, so that the electrical potential at the output end of the inductor follows the electrical potential change at an input end of the inductor to adjust the current through the inductor. The motor emulator reduces switching loss.
