Abstract

PURPOSE:To alleviate the power consumption of a power source by so switching the output side voltage of a chopper circuit as to supply the voltage to the power source of a driving circuit after the output voltage of the chopper circuit exceeds the prescribed value. CONSTITUTION:A switching circuit 8 is connected, when a chopper circuit 3 is stopped, to the output of a DC power source circuit 2, and is connected, after the chopper circuit 3 is started, to the output upon switching by the operation of the output signal from a detecting circuit 9. Since the chopper circuit 3 is automatically started by the input side voltage of the chopper circuit 3 as a high DC voltage current and is continuously operated, after the starting, by the output side voltage of the chopper circuit 3 as a low DC voltage current, the voltage drop of the driving power source supplied to the driving circuit 6 can be decreased during the continuous operation, and the power consumption of the power source 7 can be largely reduced.
