High Efficiency Unity Power Factor Compact Fluorescent Lamp with Energy Conservation Dimmer for Commercial Applications

S. Sivaram

Abstract: This paper presents unity power factor single switch ballast for CFL with intensity controlled dimmer. The circuit topology comprises of single switch electronic ballast and an intensity controlled dimmer. This single switch is operated at ZVS and it carries only input current which leads to high efficiency. This circuit will operate in energy conservation mode during activation of Dimmer otherwise it operates in constant power mode. PSIM simulation results are provided which highlights the merits of proposed work.
