Abstract

This paper presents an identification technique of parameters of a high frequency equivalent circuit of permanent magnet synchronous motors (PMSM) driven by a PWM inverter. The high frequency oscillatory currents such as leakage current to the motor frame (common-mode current) and high frequency oscillatory line current (normal-mode current), are generated by switching instants of inverter transistors. The parameters of the high frequency equivalent circuit of PMSM which can simulate the oscillating current are identified by means of genetic algorithm. It is shown that the high frequency equivalent circuit with identified parameters can generate the oscillating current by some simulation results.
