Performance Analysis of Electronic Ballast in CFL ApplicationUsing Sepic and CUK Converter Topology

摘要

This syudy is based on the reduction of power quality issues, using converter topology for CompactFluorescent Lamp (CFL) applications. While concentrating on the parameters such as Total HarmonicDistortion (THD), Power factor and output voltage DC-DC converter topology is compared. On the performanceanalysis of Single-Ended Primary-Inductor Converter (SEPIC) and CUK converter, all the above parameters forthe various duty ratio are analyzed and measured. To obtain steady state output voltage of both the converterare made to be operated in the closed loop system using PI Controller. In order to reduce the switching lossesand achieving the Zero Voltage Switching (ZVS) the switching frequency of the Series Resonant Parallel LoadedInverter (SRPLI) made to be greater than the resonant frequency. To analyze the above parameter for thevarious duty cycle value of the above converter topology are designed by using MATLAB/Simulink Model.The observed values of THD, power factor and output voltage are tabulated and compared.
