Abstract

PURPOSE:To operate the inverter without regard to the condition of load by supplying the output voltage of the inverter as the power supply of an inverter control circuit when service interruption while controlling the V/F ratio so that DC stage voltage is made constant when service interruption. CONSTITUTION:A voltage detector 9 detects the DC stage voltage, and supplies output to the PWM inverter control circuit 7 controlling the V/F ratio so that the DC stage voltage is made constant when service interruption. The ratio of transformer of a transformer 10 is selected so that the peak value of the secondary output voltage is made slightly lower than the peak value of a commercial power supply 1. A bridge rectifier 11 is connected to the filter capacitor 64 of the power supply 6' of the inverter control circuit. A service interruption detecting circuit 8' issues a command to the PWM inverter control circuit 7 so as to control the V/F ratio so that the DC stage voltage is made constant when service interruption.
