An inverter-driven induction motor drive system (40) comprising: a plurality of input lines (12,14,16) adapted to receive a three-phase alternating current input signal; a rectifier circuit for converting said alternating current input signal into a direct current signal; a gating circuit for converting said direct current signal into a variable voltage, variable frequency three-phase alternating current output signal for controllably driving said motor; a plurality of output lines (34a,36a,38a) electrically connected between said gating circuit and said motor; a ground wire (42); and a four winding common mode inductance (L1) connected on said output lines and said ground wire for reducing the electromagnetic interference produced by said systems. <IMAGE> |
