This paper deals with the high frequency equivalent circuits in an induction motor driven by a PWM inverter. The leakage current flows through stray capacitance among stator windings and iron core (frame) of the induction motor at the switching instants of the inverter transistors. The high-frequency equivalent circuits are derived based on the frequency characteristics of the high frequency zero-phase-impedance and line-to-line-impedance of the induction motor. The validity of the derived equivalent circuits is confirmed by simulation and experimental results.
