Abstract

Abstract:-In this paper we propose a high frequency unity power factor correction resonant converter for electronic ballast lamps. The change in the switching frequency of the converter changes the output voltage amplitude of the converter also changing the harmonic distortion in the output voltage and current. To maintain the input current shape the converter employs small energy tanks reducing the THD of the input current. The efficiency, THD of the converter are analyzed in MATLAB Simulink software with respect to change in switching frequency and presented in this paper.
