Abstract
A drive system for driving a multi-phase motor (such as a three-phase AC motor) or other load. Where a transformer is used, the transformer may have a disconnected wye configuration on the secondary side. The system may also utilize the average or other combination of DC bus voltages of inverters for each load phase, to provide feedback control.
