ABSTRACT:
First and second rectification circuits are connected to a commercial AC power supply by a reactor. A load is connected between the output terminal on the positive side of the first rectification circuit and the output terminal on the negative side of the second rectification circuit. While the voltage or the commercial AC power supply remains at the positive level, a current flows through a path constituted by one of the diodes of the first rectification circuit and one of the diodes of the second rectification circuit. While the voltage of the commercial AC power supply remains at the negative level, too, a current flows through the path constituted by one of the diodes of the first rectification circuit and one of the diodes of the second rectification circuit.
