Abstract
PURPOSE: To lower the usuable tail voltage for the DC power source by securing the function as the stabilizing power circuit for the DC power source at the operating time via the AC power source and the securing saturation for the serial control transistor at the reduction time of the DC power voltage.
CONSTITUTION: Automatic switching circuit 24 switches the voltage which is boosted via the power voltage obtained through load 15 by means of the control voltage obtined through the reactifier circuit, and then applies the boosted voltage to power circuit 23 only when the DC power source is used. With application of the boosted voltage, the serial control transistor within power circuit 23 is saturated at the reduction time of the power voltage. Thus the usable tail voltage can be set low for the DC power source.
