Single-Switch Single-Phase Voltage-Quadrupler Rectifier

Abstract

A single-phase voltage-quadrupler rectifier using a single active power device is presented. This is based on the combination of a half-bridge rectifier and the circuits operated in the switching states for pumping action to pump twice the peak supply voltage onto each of the output capacitors. The experimental prototype employing an insulated-gate bipolar transistor and a controller for output voltage regulation is implemented to investigate the operation. The experimental results confirm that the input current can almost be waveshaped sinusoidally with a near-unity power factor under the output voltage quadruplication.
