摘要：

This study presents a novel high-frequency three-phase permanent magnet synchronous motor (PMSM) model to predict the common-mode (CM) current and CM voltage in a pulse-width modulation inverter-fed adjustable speed drive systems. Parameters of the model are calculated based on the measured CM impedance, applying vector fitting method. The model-calculated CM impedance is compared with the experimental impedance measured on a 3kW PMSM with the star-winding connection, which has shown considerable accuracy at a frequency range of 100Hz-10MHz. The frequency-domain analysis of CM voltage and CM current is then predicted by using the proposed circuit model in MATLAB/Simulink, which gives good agreement between calculated and the measured results.
