Abstract

PURPOSE: To provide an operation of stabilized control for the DC output voltage, by making a rate of interruption variable for a second switching element, with the second switching element, for use of rectification and interruption controllable, provided at secondary side of the transformer.
CONSTITUTION: After rectifying square wave AC from secondary side winding N2 of a transformer 2 through a main switch S2 21 that consists of a series switching transistor, a prescribed DC voltage V0 is taken out through a low-pass filter that consists of a series inductance 9 and a parallel capacitance 10. With this output voltage V0 detected and amplified by an amplifying circuit 11, the rate of interruption of the main switch S2 21 is made variable by a control circuit 22, and a stabilized control of the output voltage V0 is operated.
