Abstract :
In this paper, a sepic-type single-stage electronic ballast (STSSEB) is proposed. The ballast system can not only achieve high power factor but can reduce voltage stress, improve efficiency and lower cost. Since component stress is reduced significantly, the presented ballast can be applied to high input voltage system. Derivation of the STSSEB is first presented and analysis, design and practical consideration for the STSSEB are then presented. A 347Vac 60W prototype has been simulated and implemented. Simulations and experimental results have verified the feasibility of the proposed STSSEB.
