Single-Phase Voltage-Quadrupler Rectifier Reducing Input Current Distortion

Abstract

A single-phase voltage-quadrupler rectifier with reduced input current distortion is presented. This can be operated in the switching states for pumping action to pump twice the peak supply voltage onto each of the output capacitors and for forcing the input current to follow its sinusoidal reference in the vicinity of a zero crossing of the supply. The experimental prototype, using two dual-switch power modules with IGBTs and a controller for output voltage regulation, is implemented to investigate the operation. The experimental results confirm that the input current can be waveshaped sinusoidally with a near-unity power factor.
