Three-Phase Inverter Simulation

In this article, we provide a comprehensive overview of three-phase inverter simulation using Simulink. We begin by examining the fundamental principles and structural configuration of three-phase inverters, including their power electronic switching mechanisms and output waveform generation. Subsequently, we delve into the step-by-step methodology for Simulink simulation, detailing how to construct the inverter model using key blocks such as PWM generators, IGBT/MOSFET bridges, and LC filters. The implementation covers parameter configuration for carrier frequency modulation, dead-time settings, and voltage/current feedback loops. Furthermore, we address common simulation challenges like harmonic distortion minimization, switching loss optimization, and real-time controller interfacing, along with practical solutions using FFT analysis tools and PID tuning techniques. Finally, we summarize the core concepts and propose future research directions for advanced applications of three-phase inverter Simulink simulation in renewable energy systems and motor drives.
