Abstract

The design and analysis of a new single-switch soft-switching class E electronic ballast with high input power factor is presented. Design equations for the optimum operating condition are derived and complete computer analysis is performed. It is shown that low duty cycle control of the class E ballast can reduce the voltage stress of the controlled switch. A 40 W fluorescent lamp ballast is implemented and the experimental recordings verify the analytical results
