Abstract

PURPOSE:To dispense with a transmission circuit and an oscillation circuit and simplify the construction of a stabilized DC powder supply circuit, by picking out synchronizing pulses from the secondary winding of a transformer and supplying the pulses to a control circuit. CONSTITUTION:The stabilized DC power supply circuit comprises a primary circuit for changing the output of a DC power source 1 into pulses by a DC-AC inverter circuit 2, secondary circuit having a DC power stabilization circuit wherein a rectification smoothing circuit 9, a switching circuit 8 and a smoothing circuit 10 are connected to one another in this order, a differential amplifier 6 for detecting the difference between the output of the secondary circuit and a reference output, and the control circuit which syntherizes the difference with the synchronizing pulses and supplies the synthesized signal to the switching circuit 8. The synchronizing pulses are picked out from the secondary winding of the transformer 4. Althrough a conventional method of DC-side control is adopted, no oscillation circuit and transmission circuit are needed and the stabilized DC power supply circuit which does not perform unstable action and whose reliability is high is obtained.
