Abstract
A device for controlling the voltage reducing ratio of autotransformer in accordance with the AC input voltage, which is characterized in that the device comprises: an autotransformer which is formed of a first coil comprising a serial coil (W1) and at least first and secondary branch coil (W2, W3) being connected in series and a secondary coil comprising the first and secondary branch coil; two bidirection switch devices (SW1, SW2) for switching control to make only the first branch coil connected to autotransformer or make both the first and secondary branch coil connected to autotransformer or make both the first and secondary branch coil disconnected from autotransformer; and an autotransformer control device for controlling the operation of the bidirection switch device in accordance with the AC input voltage supplied to the first coil.
