This paper deals with leakage current and it's high-frequency zero-phase-sequence equivalent circuit in an induction motor driven by a PWM inverter. The leakage current flows through stray capacitances between stator windings and iron core (frame) of an induction motor at the switching instants of the inverter transistors. The high-frequency zero-phase-sequence equivalent circuit is derived based on the frequency characteristics of the high-frequency zero-phase-impedance of the induction motor. The validity of the derived equivalent circuit is confirmed by simulation and experimental results.
