Abstract

This paper presents a simple configuration of a high power factor electronic ballast. The proposed approach makes an integration of two power processing stages, a boost power converter and a self-excited series resonant inverter. The self-excitation mechanism makes a merit of self-adjustment on the inverter duty-ratio resulting in an almost unity power factor at the input line. Experimental tests are carried out an the circuit designed for a 36-W compact fluorescent lamp
