Abstract
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 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 experimental recordings verify the analytical results
