Single-Phase Unipolar PWM Inverter

Simulates a unipolar single-phase inverter using SPWM in MATLAB/Simulink for efficient DC–AC conversion with low harmonic distortion

This model shows how a single-phase inverter converts DC power into AC using four MOSFETs arranged in an H-bridge. The switches operate in a specific sequence to generate a smooth AC output waveform from a DC source. By using the unipolar SPWM technique, the inverter produces a cleaner output with lower harmonic distortion. It’s a simple and effective way to understand how DC is converted to AC for single-phase applications.
