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. © 2009 Wiley Periodicals, Inc.
