This paper presents the design and performance of an electronic ballast which provides a constant light output for wide input voltage fluctuations from 85V to 265V. Two IC's have been used in the design: the first part has a PFC controller IC and the second part IC is a ballast driver. The PFC circuit produces and maintains a constant power factor and a constant voltage of 400 V. The second part,...
