Comparison and Design of Flyback Converter using an Ideal Switch and a MOSFET Switch

Abstract

The Flyback Converters have become one of the most popular used buck-boost topology because of their simple design and working efficiency. In this paper, the dynamic models of the flyback converter using two different switches have been compared. One using an ideal switch and other using a MOSFET switch. These models have respective advantages for example single switching, coupled inductor, output filter (capacitive), isolation and operating of these models at a particular value of frequency in a traditional PWM scheme. In the MOSFET Switch Flyback converter the PWM percentage period of Input Output can be increase or decrease. To access apparent parameters, a model is simulated to find the transformer parameters, capacitive parameters, frequency of operation. A simulation model for this purpose in MATLAB/SIMULINK has been devised and then affirmed by running this model on the simulation platform. Also to find its various performance matrices with their verification.
