Power factor correction using a boost quasi-resonant converter

Abstract

A steady-state analysis of a quasi-resonant zero current boost converter is performed in its application to a single-phase power factor correction circuit. The known closed-form expressions are used to design the boost converter and the multiloop control circuit. The operating characteristics are simulated by using PSPICE and are experimentally verified. Considerations for a practical design are based upon hardware operating at a maximum of 1 megahertz, with a 115 VRMS input, 200 VDC and 100 watt output.
