Abstract

PURPOSE:To separate a direct current component of input and that of output and provide a simple circuit configuration, by a method wherein the frequency switching primary winding is controlled by a photo-coupler. CONSTITUTION:When input is given from a direct current power source, output voltage is zero at first, and no controlling signal comes out of a phot-coupler 8. Therefore, an oscillator 1 generates a resonance frequency, and an exchanging circuit 2 and a switching circuit 3 are driven by that frequency, so that the output voltage is given to a commutator circuit 5 and a regulator 6. When the output voltage of the commutator circuit 5 rises to the value preset by an error detecting circuit, the frequency of the oscillator 1 is controlled. With said method, the output voltage of a rectifying circuit 5 is kept constant.
