Abstract
A power conversion apparatus for converting direct current from a power source to polyphase alternating current includes a plurality of carrier signal generators, a plurality of gate signal generators, and a plurality of legs. The carrier signal generators are configured and arranged to independently generate and transmit a plurality of carrier signals, respectively. The gate signal generators are operatively coupled to the carrier signal generators, respectively, to receive the carrier signals, each of the gate signal generators being configured and arranged to generate an on/off signal by comparing a command value of each phase of the polyphase alternating current and corresponding one of the carrier signals. The legs are connected to the gate signal generators. Each of the legs is operated based on the on/off signal transmitted from corresponding one of the gate signal generators to convert the direct current to each phase of the polyphase alternating current.
