<p>A drive and recharge apparatus is disclosed that includes a bidirectional dc power source (26), two voltage-fed inverters (40a,40b), two induction motors (12a,12b, and a control unit. In the drive mode, power is bidirectionally connected between the dc power source and the motors. In the recharge mode, single-phase power applied to the neutral ports (66a,66b) of the two motors is converted with unity power factor to return energy to the dc power source. An alternate scheme is also presented which uses a single motor having two sets of windings. <IMAGE></p> |
