MATLAB-based Simulation of Single-Phase Full-Bridge Inverter using Sinusoidal Pulse Width Modulation (SPWM)

Detailed Documentation

We conducted a MATLAB simulation of a single-phase full-bridge inverter utilizing Sinusoidal Pulse Width Modulation (SPWM) technique. The simulation involved comprehensive analysis to understand the system's operational principles and performance characteristics. Our implementation included signal sampling and processing modules to emulate the complete inversion process, with detailed analysis of output waveforms using MATLAB's plotting and FFT functions. The simulation code incorporates PWM generation algorithms comparing carrier signals with sinusoidal references to control switching devices. Furthermore, we investigated the impact of various system parameters such as modulation index, switching frequency, and filter components on output quality, enabling system optimization through parameter sweeping techniques. This simulation study provides valuable insights into inverter dynamics and establishes a foundation for further research and improvement of power conversion systems.
