Abstract

PURPOSE: To achieve cost down, by controlling other DC output voltages at the same time through the regulation of one representative DC output voltage and regulating all the DC output voltages.
CONSTITUTION: A resistor or a coil 4 is connected between the AC input terminal 9 and the input terminal 7 of the power supply transformer 1, and the voltage regulating circuit 3 is inserted between the rectifying smoothing circuit 2 and the DC output terminal 6, then the voltage V6 appeared at the terminal 6 is changed with the current Ic flowing to the controlling transistor 3', allowing to regulate the voltage V6 through the control of Ic. On the other hand, when the voltage V6 is regulated, the DC output voltages appeared at the terminals 6'W6n' are also regulated in proportion to the secondary winding ratio of the transformer 1. Accordingly, if the specifications require tight regulation to one DC output voltage and do not call for so tight requirements to other DC outputs, this method is very effective.
