IPC: H02M7/06
Filed: 1994-09-02
Abstract: PURPOSE: To improve the power factor of a DC power supply device. CONSTITUTION: In the DC power supply device, a capacitor 5 discharges electricity for a period when an FET 1 is brought to an on state, and an output current IOUT1 . is made to flow through load 10 through a DC feeder circuit 8 from a rectifier circuit 7 for a period when the FET 1 is brought to an off state.
