Abstract

PURPOSE: To reduce power loss and surely operate a control circuit, by driving the control circuit through a stabilization circuit for a prescribed time after the starting of power application and thereafter driving the control circuit through an auxiliary power supply circuit including the tertiary winding of a main transformer.
CONSTITUTION: When a switch SW is closed, a stabilized voltage is applied to the control circuit CC through a resistor RP and a Zener diode ZD to operate a switching element MT to generate on output on the secondary winding NS of the transformer TF. The output of the tertiary winding of the transformer TF is rectified and smoothed by the auxiliary power supply circuit connected to the control circuit CC. When an output voltage is stabilized, a relay Ry is operated to switch the stabilized voltage to the auxiliary power supply circuit. Since the stabilization circuit is used only in the initial stage of power application, no stationary power loss takes place in the stabiliation circuit. As a result, the total power loss is reduced and the efficiency is raised.
