Abstract
A filter for a motor drive includes a plurality of phase lines configured to connect an output of a power source to an input of a motor. The power source is configured to supply at the output a voltage that switches between a high voltage state and a low voltage state. The filter includes a plurality of capacitors, where each capacitor is connected between one of the plurality of phase lines and a ground. The filter further includes a plurality of primary inductors, where each phase line includes one of the plurality of primary inductors. The filter includes a plurality of secondary inductors and a plurality of resistors. Each secondary inductor is connected in series with one of the plurality of resistors and each primary inductor is connected in parallel to one of the plurality of secondary inductors and one of the plurality of resistors.
