Abstract
This paper deals with an almost unity power factor (UPF) improved power quality based electronic ballast. The proposed electronic ballast consists of a PFC (power factor corrected) SEPIC (Single Ended Primary Inductance Converter) converter, which operates in discontinuous conduction mode (DCM), and a high frequency dc-ac inverter. The design, modeling and simulation of PFC based electronic ballast for a compact fluorescent lamp are carried out in MATLAB-SIMULINK environment for a 220V, 50 Hz lamp at constant dc link voltage. In the proposed topology, a half bridge parallel loaded resonant inverter is used to feed constant current to lamp for universal voltage applications. The power quality indices are calculated such as total harmonic distortion of ac mains current (THDi), power factor (PF), displacement power factor (DPF) and crest factor (CF) to study the behavior of UPF electronic ballast.
