Simulation of PWM Control for Inverters (All PWM Techniques)

This document addresses the simulation of Pulse Width Modulation (PWM) control for inverters, focusing on various existing pulse width modulation techniques. It should be noted that PWM control is used to regulate the power output delivered by inverters and can be applied to all PWM methods. We will examine in detail the different PWM techniques that can be implemented, including their advantages and disadvantages. The implementation typically involves generating switching signals using carrier comparison methods, where sinusoidal modulation waves are compared with triangular carrier waves to produce gate signals for power switches. We will also cover different types of inverters that can be controlled using PWM techniques, such as single-phase and three-phase voltage source inverters, and discuss the most suitable applications for each technique. Finally, we will explore various simulation methods available for PWM control implementation, reviewing the benefits and drawbacks of each approach, including MATLAB/Simulink modeling with specialized power electronics blocksets and Python simulations using libraries like SciPy for waveform generation and control algorithm development.
