Abstract

PURPOSE: To ensure the change-over from starting circuit to auxiliary power source without increasing power loss, by using a Zener diode for stabilizing output of starting circuit and auxiliary power source together.
CONSTITUTION: Electric current from power source E is supplied for the primary winding L1 of transformer T through switching element QS whose conductivity is controlled by driving circuit 1 and from the secondary winding L2 of the transformer output VO is obtained. This regulator is equipped with starting circuit 2 for supplying driving circuit 1 with power source at the starting time and auxiliary power source 3 for supplying power source after starting. Although auxiliary power source 3 is applied for filling capacitor C1 with the current from coil L3 of transformer T, the Zener diode for stabilizing voltage of this power source 3 is used together with Zener diode DZ for stabilizing output used in starting circuit 2. Diode D3 prevents reverse current.
