Comparison of Fly-back Converter and Reverse Fly-back Converter for PV Applications

The Converters of DC-DC have a wide range of applications as an intermediate stage converter in order to improve the power factor at desired value and reduce the harmonics at a better rate by shaping the alternating current before and after the load supplying the DC converters and rectifiers respectively. In recent years reverse fly-back converters got a popularity because of their features like the most efficient and simple construction with a feature of fly-back topology. In this paper the differences between reverse fly-back and fly-back converter in different aspects like Total output voltage, Total output current and total harmonic distortion (THD) are presented. Petroleum and coal are the available natural resources to generate the Electrical energy in the world and the reserve of these sources are decreasing. Alternative energy sources are like wind, solar, biomass, hydro, marine energies, geothermal. Solar is the most important in these sources. In recent years huge developments are happens in study on solar energy. This research is purely on developing the power electronic converters in orders to produce the continuous output for discontinuous input by just controlling the duty cycle of the switches. In order to get a maximum amount of power form PV array different algorithms in MPPT is required. The mathematical modelling and analysis are designed with given parameters and tested with MATLAB/SIMULINK simulation.
