Design and analysis of Push-pull-Flyback interleaved converters for photovoltaic system

The ease of expansion of power system and lowered cost made the use of modular converters in Renewable Energy System more common. Different configurations are implemented depending on the applications. Control strategies like fuzzy logic, droop method and charge control scheme are developed for achieving sharing of current and voltages among the converters. In this paper new modularization architecture is proposed with two different converters i.e., Push-pull and Flyback converters. This architecture has the full benefit of modularization through the sharing of current and voltage. Simulation analysis and experimental prototypes are built and tested to ratify the sharing of input and output current and voltages of proposed architecture.
