Abstract :
An interleaved single-stage power-factor-correction (PFC) electronic ballast is presented in this paper. The proposed ballast is combined by two interleaved boost cells and a conventional half bridge DC/AC inverter. Each boost cell operates in discontinuous conduction mode so that a high power factor is achieved naturally. By exploiting the interleaving technique, the input ripple current of the electronic ballast is reduced. Theoretical analysis and experimental results for two 45-watt fluorescent lamps are presented
