ABSTRACT:
A rectifier circuit for receiving an A.C. electrical power signal at a pair of circuit input terminals and for providing a rectified, D.C. electrical power signal at a pair of circuit output terminals includes a primary transformer winding connected to receive the A.C. electrical power signal, a plurality of secondary transformer windings, and a semi-conductor rectifying and switching circuit which supplies a D.C. electrical power signal to a storage capacitor connected across the circuit output terminals. A control circuit sequentially actuates the semi-conductor switches such that differing combinations of the secondary transformer windings are sequentially connected across the storage capacitor during each successive half cycle of the A.C. electrical power signal. By this arrangement, the charging current supplied to the capacitor and the charging potential across the capacitor fluctuate minimally during most of each half cycle and the A.C. electrical power signal is not substantially distorted in waveshape.
