<p>In a multi-output power conversion circuit which drives a polyphase AC motor (603) and another device but the polyphase AC motor (603) using a DC power source (601), a transformer (1 01) is connected to the neutral point of the polyphase AC motor (603), an AC voltage at a zero-phase voltage frequency is obtained from the transformer (101), and the other device is loaded with the AC voltage. <IMAGE></p> |
