High Gain DC-DC Converter for Photovoltaic System

Abstract

The, high-gain DC–DC converters dragged much attention among the researchers. But there is a concern that high-gain converters have less efficiency and high switching stresses. The converter topology has two quasi-impedance source network and a voltage multiplier cell unit to facilitate very high-gain output voltage. The input variations due to varying irradiation of photovoltaic are alleviated by employing the perturb and observe maximum power point tracking mechanism. The simulation of the work is realized in MATLAB/ Simulink arena, and hardware circuits are validated using the dsPIC30F2010 controller. Key Words: High-gain DC–DC converter, non-linear carrier controller, voltage regulation, perturb and observe maximum power point tracking, solar photovoltaic
