Abstract
PURPOSE:To enable to supply an electric power necessary to start a motor without increasing the capacity of an inverter by reducing the transformation ratio of an output transformer interposed between the inverter and the motor only at the starting time. CONSTITUTION:A contactor 5 is thrown only at the time of starting a motor M to bypass as output transformer 3, the output current of an inverter 2 is supplied to the motor M as it is, and a current necessary to start the motor M is applied to the motor. When the motor M is started, the contact 5 is opened, and the contactor 4 is simultaneously thrown, and the output current of the inverter 2 is supplied through the output transformer 3 to the motor M. In this manner, the current necessary to start the motor can be supplied to the motor without increasing the capacity of the inverter.
