PURPOSE:To minimize the input power of an inverter by providing an output voltage correcting circuit. CONSTITUTION:A correcting polarity instructing circuit 40 receives a signal of a discriminator 20 and instructs the polarity of a correcting signal of an output voltage command. The output of the circuit 40 turns ON either one of the switch 52 or switch 53 of an output voltage correcting circuit 50. In an ordinary state, the output voltage correcting voltage is applied to an output voltage controller 7 so that the inverter input current is minimized by alternately turning ON and OFF the switches 52, 53. |
