Three Phase VSI using SVPWM Technique for Grid Connected PV System

Abstract

  Solar energy is one of the most promising Renewable Energy Sources (RES) that can be used to produce electric energy through Photovoltaic (PV) process. The Solar Photovoltaic (SPV) system which is directly supply power to the grid is becoming more popular. A power electronic converter which converts DC power from the Photo voltaic array to AC power at required voltage and frequency levels is known as Inverter. Generally different Pulse Width Modulation (PWM) methods have been implemented for grid connected 3-phase Voltage Source Inverter (VSI) system. This thesis defines few types of PWM techniques and mathematical model of LC filter circuit is given using state space analysis.
