。[Claims for Utility Model Registration] A transformer with a tap to which AC power is applied to the primary side has each secondary terminal connected to a load via an output selection switch, and based on voltage detection of the AC power, an alternating current constant voltage that selectively turns on each of the output selection switches to selectively supply the output of each of the secondary side terminals to the load to suppress fluctuations in load voltage based on voltage fluctuations of the alternating current power supply; In the apparatus, a switch circuit for a normal power supply line is provided between a load-side coupling point of each of the output selection switches and the load and is controlled to be turned off only when the voltage of the AC power source fluctuates; an inverter device that is driven according to the amount of variation in load voltage; and an injection transformer for series compensation whose primary side is connected to the inverter device and whose secondary side is provided in parallel with the switch circuit, An AC constant voltage device, wherein the inverter device absorbs an excess or deficiency of the load voltage from a rated voltage based on the output of a secondary side terminal.
