Abstract

This paper presents a power factor correction (PFC) rectifier for single-phase offline converters. With the addition of a charge pump circuit comprised of a capacitor and a diode to a class-DE series-resonant converter, PFC is achieved inherently. The converter operation is based on soft-switching, and a 1 MHz 50 W prototype employing wide bandgap devices is implemented, achieving a power factor of 0.99 and a total harmonic distortion (THD) of 8.6 %, at an efficiency of 84 %, with substantially low input current harmonic magnitudes compared to the limits set by the IEC 61000-3-2 standard.
