摘要：

A PWM inverter with an induction motor often has a problem with a leakage current that flows through the distributed electrostatic capacitance from the motor windings to the ground. This paper presents an analytical model of the system with leakage current and the strategy to suppress it. Two types of suppression circuits are discussed. The current-type circuit, although compact in size, not only acts as an excellent suppressor but also becomes a high-performance filter of the output voltage.
