Comprehensive Study on 3-phase PWM Inverter for Grid Connected PV Generation System using SPWM technique

Author Name : Preeti Sharma, Ms. Poonam Nandal,

Inverter is the most important device to utilize the renewable energy sources efficiently. The Sinusoidal Pulse Width Modulation (SPWM) technique is one of the most popular PWM techniques for harmonic reduction of inverters since there are used three sine waves displaced in 1200 phase difference as reference signals for three phase inverter. Nowadays the SPWM switching signal is generated with the help of different FPGAs, microcontrollers and microprocessors. But for these kind of devices it is necessary the programming or coding. This paper represents the SPWM technique for harmonic reduction & shows how to generate SPWM switching signal using different simple Operational-Amplifier (Op-Amp) circuits/analog circuits for three phase pulse width modulated (PWM) voltage source inverter (VSI).
