Comparative Analysis of Modulation Methods for Optimizing the Performance of Single-Phase Full-Bridge Inverters

In this research, several pulse width modulation (PWM) methods utilized in single-phase inverters are compared. There are two inverter circuit cases examined. Case i: Using a variety of PWM approaches, including saw-tooth, random, square, and sinusoidal pulse width modulation (SPWM), an analysis is conducted for an inverter circuit with a constant resistive load. Case ii: total harmonic distortion (THD) of voltage and current is verified using an analysis based on the traditional PWM approach with resistive inductive loads. Use of the MATLAB/SIMULINK tool is used to validate the simulation. The results demonstrate that the random PWM approach outperforms other methods in terms of performance.
