Abstract
One of the most popular PWM techniques for controlling the output and harmonic inverter decreased is indeed the sinusoidal pulse width modulation (SPWM) technique. In PWM modulating techniques, recent developments in power electronics and semiconductor technology have lead to the use of upper carrier frequency. The RL load is connected with an LC filter in the presented voltage source inverter. A sinusoidal (SPWM) PWM and the third harmonic injection (THIPWM) PWM are two PWM techniques used to operate converter for voltage source. The results of the simulation reveal that THIPWM outperforms then SPWM A MATLAB Simulink demonstrates and compares both techniques to THD.
