PWM Rectifier Simulation Model

The PWM rectifier simulation model serves as an excellent research tool for analyzing rectifier circuit behavior. This custom-built model implements controlled rectification through pulse-width modulation techniques, allowing precise voltage regulation and power factor correction. The simulation structure typically includes PWM signal generation modules, switching device drivers, and feedback control loops that maintain stable DC output under varying load conditions. Key implementation aspects involve configuring IGBT/MOSFET switching patterns, designing voltage/current controllers using PI or PR control algorithms, and implementing phase-locked loops for grid synchronization. Users can modify parameters like carrier frequency, modulation index, and filter components to study harmonic distortion, efficiency optimization, and dynamic response characteristics. The modular design facilitates easy customization of circuit topologies (such as single-phase or three-phase configurations) and enables comparative analysis of different control strategies. This makes the model particularly valuable for engineering students and researchers developing advanced power conversion systems, providing hands-on experience with real-time simulation and hardware-in-the-loop testing methodologies.
