Modeling and Performance Analysis of Single Stage Power Factor Corrected Resonant Converter Using MATLAB/Simulink

The projected technique is based on the utilization of customized three-level resonant converter topology to increase their power ratings to be in several kilowatts levels. In this technique low voltage stress on switches, made possibility of operation with high frequency, possibility of zero voltage switching, can be applied under a wide range of input and output conditions including high flexibility in operation and control can be achieved using the principle of combined control of frequency and asymmetrical pulse width modulation. In proposed technique the output voltage is regulated through the variation of frequency and input power factor correction are obtained through pulse width modulation control. The proposed topology of converter has been implemented and investigated in the MATLAB/Simulink and the various results are provided to validate the proposed concepts.
