Abstract

PURPOSE:To reduce a current supplied from an input power source to a drive control circuit by comparing the power voltage of the control circuit with a set value to operate and stop it, and raising the set value at stopping time as compared with that at operating time. CONSTITUTION:A DC voltage V1 is supplied from a DC input power source 1, a capacitor 10 is charged, its voltage V10 gradually increases. When V10 becomes higher than a set value VH, a power voltage monitor 13 supplies a drive signal to a drive control circuit 6, and reduces the set value to VL. When the control circuit 6 is operated, a large current is supplied from a resistor 12 to the control circuit 6. Thus, the voltage V10 of the capacitor 10 drops. However, since the control circuit 6 starts supplying a drive signal to a converter 2 before the voltage V10 becomes lower than the set value VL, power is supplied from a tertiary winding N3 by the voltage applied to the primary winding N1 of a transformer 3 to the control circuit 6 and the capacitor 10, the V10 again rises, and the control circuit stably operates.
