Design and Analysis of Interleaved Flyback Converter Topology for Photovoltaic Applications

All over the planet, there is a great demand for and need for electrical energy utilization. The market for non-conventional energy sources is increasingly growing and demand shoots up. Renewable energy resources play an important role among which Photo Voltaic (PV) cell electrical energy is the most reliable and effective one for power generation. The analysis of various converter circuits leads to show that, an interleaved fly-back converter topology in isolated grid associated inverter for high power photovoltaic applications is best even under partial shading conditions. A special mechanism known as an interleaving concept is used in this paper and it is an essential phenomenon in order to achieve high power as well as minimize the ripple components in current waveform. By the implementation of the proposed method, we acheived reliable percentage efficiency is 98.08 and the power factor for the system is 0.925.
