Abstract:
An apparatus and method for supplying a polyphase (AC) alternating current motor with driving voltages. A conversion unit is coupled to phases of the polyphase AC motor and includes a plurality of switching devices and includes, in at least one phase, a first switching device between a bus of an AC power supply and an output terminal, a second switching device between a bus of a direct current (DC) power supply and the output terminal, and a third switching device between a common bus for the AC power supply and the DC power supply and the output terminal. Driving voltages for the polyphase AC motor are generated by selecting a voltage from among voltages having potential values corresponding to the AC power supply and the DC power supply, and the selected voltage is used to operate a switch of the plurality of switching devices.
