ABSTRACT:
An apparatus for controlling the operation of an inverter which converts DC power obtained by rectification of a received AC power or DC power received from a battery which is alternatively actuated in case of an AC power supply failure or the like, into AC power. The inverter control apparatus includes a first control means which detects the output voltage of the inverter to thereby control the operation of the inverter in accordance with the detected value of the inverter output voltage. The inverter control apparatus further includes a detector for detecting variations in the input voltage of the inverter and second control means for controlling the width of the firing angle which is controlled by the first control means, in accordance with the detected value of the inverter input voltage variations, so that variations in the output voltage of the inverter may be suppressed even in the case of occurrence of variations in the input voltage of the inverter.
