The Influence of Inverter,s Output Voltage du/dt on the Motor and Its Filter Design

Abstract

This paper studies the influence of inverter’s output voltage du/dt on the end voltage and bearing current of the motor, sets up the motor high-frequency model in PSpice and stimulates waveforms of the end voltage. It stresses on the design method for the parameters of du/dt filter and verifies the simulation in PSpice. These results testify that the filter has the better effect.
