Simulation of High Power Factor Single Phase Inverter for PV Solar Array

Photovoltaic (PV) systems are solar energy supply systems, which either supply power directly to an electrical equipment or feed energy into the public electricity grid focuses on the latest development of modelling and control of grid connected photovoltaic energy conversion system this paper is depicts information about dc-ac inverter used in solar inverter. We will get DC power from solar panels and this converter inverts DC to AC. This design and modulation is based on MATLAB software. In circuit, for switching purpose IGBT is used. There are many other devices also but IGBT has more advantages than others which are shown by comparison with others. The main thing is that this conversion and switching of IGBT is done using different types of PWM methods. Here we are using SPWM method for conversion of AC power and HCC-pulse width modulation. This method is very efficient than other methods. In this paper we proposed Double-band HCC-ler method. Project objective are, to design an inverter model by using MATLAB and making analysis on the output voltage and to study the function of PWM in single phase inverter. Project scope is: 1) Modeling and simulation using MATLAB. 2) Using PWM method for the switching operation. Project application: This Project is based on solar inverter; this inverter will be used in our college for lab applications.
