PWM Implementation for Single-Phase Bridge Inverter Circuit

Single-phase bridge inverter circuits represent a fundamental power conversion topology primarily designed to convert DC power into AC power. This circuit utilizes Pulse Width Modulation (PWM) techniques to control the switching operations of power semiconductor devices, enabling precise regulation of output voltage characteristics and frequency parameters. This resource provides a fully functional MATLAB implementation (verified compatible with MATLAB 7.0) that models PWM-controlled single-phase bridge inverter operation. The MATLAB script incorporates key algorithmic components including carrier wave generation, modulation index calculation, and switching logic implementation using comparison operations between reference and carrier signals. The implementation enables comprehensive analysis of inverter performance metrics including output voltage waveforms, current characteristics, power calculations, and harmonic distortion assessment. Through structured parameter configuration and simulation execution, users can validate theoretical concepts, optimize circuit design parameters, and gain practical insights into inverter control strategies. The code architecture facilitates modification of modulation indices, switching frequencies, and load conditions for extended research applications.
