MATLAB Simulink Implementation of PWM Inverter with Power Electronics Simulation

This document discusses the implementation of a PWM inverter using MATLAB Simulink. A PWM inverter is a power conversion device used to generate alternating current (AC) power from direct current (DC) sources. This type of inverter is widely used in industrial applications due to its high energy efficiency and relatively straightforward power conversion process. MATLAB Simulink is a numerical analysis software specifically designed to provide simulation environments, which has become extensively utilized in the field of power electronics. The implementation typically involves using Simulink's Power Systems library components such as IGBT/MOSFET switches, pulse width modulation generators, and LC filters. Key implementation aspects include configuring the carrier signal frequency, modulation index, and dead-time parameters in the PWM generator block to control output voltage waveform quality. Therefore, mastering PWM inverter implementation using MATLAB Simulink represents a crucial skill for engineers working in power conversion technology. The simulation approach allows for testing different control strategies like sinusoidal PWM or space vector modulation before hardware implementation, reducing development time and cost while optimizing system performance through parameter tuning and waveform analysis capabilities.
