Abstract
A motor drive system for driving a conventional single phase PSC motor from a two-phase power source which allows for convenient motor direction reversal. In one embodiment, the PSC motor is supplied from a three-phase inverter that is controlled to generate two-phase power. In another embodiment, the PSC motor is connectable through a double-pole double-throw switch to either a single phase source including a run capacitor or a two-phase inverter source.
