Abstract
PURPOSE: To obtain a self-oscillation system stabilized power source, with the output voltage stabilized not by using a stabilizing regulator as well as with a power loss reduced further with a number of part items reduced.
CONSTITUTION: With AC power source rectified by a full-wave rectifier circuit CR1, a DC output Vp, smoothed out by a condenser C1, is connected to a primary winding T1 P of a high frequency transformer T1 through a power transistor Q1, and converted into an AC voltage by the action of oscillation caused between the power transistor Q1 and the transformer T1. Outputs obtained from secondary windings T1S1, T1S2 of the transformer T1 are rectified and smoothed with output voltages VA, VB obtained. A change of the output voltage VB is detected by a photocoupler Q3, with a base current of the power transistor Q1 controlled through a transistor Q2 correspondingly to the change of the output voltage, thus enabling the output voltage VB and VA to be kept constant.
