Power factor correction circuit for low-cost electronic ballast using current-source type push-pull resonant inverter

Abstract

A new low-cost high power factor correction circuit for electronic ballast employing current-source type push-pull resonant inverter (CS-PPRI) is proposed. The proposed circuit provides good power factor correction, low current harmonic distortion and cost-effectiveness. The prototype meets the IEC555-2 requirements satisfactorily.
