Abstract :
In this paper a new solution to implemented single-stage high-power-factor electronic ballast based on integrated buck DC-DC converter and a half-bridge resonant inverter is presented. The buck converter is operated in discontinuous conduction mode and at constant frequency providing an input power factor high enough to satisfy present standard requirements. The operation of the proposed ballast is also investigated in detail in this paper. A ballast prototype for 2×36 W fluorescent lamps has been simulated and implemented at the laboratory
