Abstract:
An integrated motor drive and battery recharge apparatus includes a battery, an electric motor having N separate motor windings each having a first and a second leg, a contactor having a plurality M of poles, each pole having a first side and a second side, the inverter having 2N switching poles and a capacitor each coupled in parallel with the battery, and PWM control circuitry configured to control the state of each switching pole. Each leg of each motor winding is coupled to a phase node of a corresponding inverter switching pole, at least two of the motor winding legs (or taps thereof) are coupled to the corresponding first sides of the contactor poles, a power source/sink is coupled to the corresponding second sides of the contactor poles, and in one aspect a capacitor is coupled between each pair of contactor poles.
