ABSTRACT:
In a power source circuit, an AC voltage of a commercial AC power source is full-wave-rectified by a diode bridge and divided into two 1/2 voltages by two capacitors connected to the output terminals of the diode bridge. A half-bridge inverter operation is performed by a smoothing capacitor and first and second reverse-conductive switches connected in parallel with the output terminals of the diode bridge via inductors, respectively. A power from the capacitors is temporarily stored in the inductors, and the first and second reverse-conductive switches are operated, thereby performing two boosting chopper operations.
