Analysis of different flyback Converter topologies

High step-up dc-dc converters have been widely used in the green energy systems. In this paper an analysis of different flyback Converter topologies are proposed. Generally it is more suitable for high voltage and low power (less than 100 W) applications. Its main features are simplicity, low cost and galvanic isolation. In the recent years, many different topologies have been discussed. Important topologies such as Active Clamp, RCD Snubber, Dual output AC and DC, Two Switch and Interleaved flyback Converters are analyzed. Functionalities of these converters are simulated using Matlab and their results are compared.
