Design and Simulation of a 3-Phase SPWM Inverter in MATLAB Simulink

Welcome to Simuscope! In this video, we design and simulate a complete 3-phase SPWM inverter in MATLAB Simulink and understand how DC voltage is converted into controlled 3-phase AC output using high-frequency PWM switching. Model available in: https://simuscope.gumroad.com/l/vwfrfl This tutorial explains: • Structure of a 3-phase inverter • Operation of IGBT switching legs • Sinusoidal PWM (SPWM) generation • Carrier and reference signal comparison • Gate pulse generation for T1–T6 switches • Three-phase output waveform analysis • RMS voltage calculation • Filtered vs unfiltered inverter voltage • Harmonics and PWM switching behavior • Role of LC filters and motor inductance The model demonstrates how modern: ✔ VFDs ✔ Solar inverters ✔ EV motor drives ✔ UPS systems ✔ Industrial motor controllers generate smooth AC power from a DC source.
