Single-Phase Switch-Mode Voltage-Doubler Rectifier Using Pump Circuits

Abstract

A novel single-phase voltage-doubler rectifier operating in the switch-mode is presented. This is based on a diode pump circuit, in which the voltage across the boost capacitor adds to the supply to pump twice the peak supply voltage onto the output capacitor, and an only power switching device provides the necessary control over the current. The arrangement tested, using an insulated-gate bipolar transistor and a controller for output voltage, is implemented to investigate the operation. The experimental results confirm that the input current can be sinusoidally waveshaped with a near-unity power factor under the output voltage duplication.
