Simulation Circuit of Three-Phase Fully-Controlled Rectifier Bridge Using IGBT Components

This paper presents a simulation circuit of a three-phase fully-controlled rectifier bridge using IGBT components. In this circuit, the three-phase AC power supply is controlled through IGBT switches, and after passing through the rectifier circuit, a more stable and reliable DC power supply can be obtained. The simulation is implemented using MATLAB/Simulink software to validate circuit performance and effectiveness, utilizing power electronics toolbox components for accurate IGBT modeling and pulse-width modulation (PWM) control strategies. Additionally, we analyze the roles and impacts of various components in the circuit, along with optimization and improvement methods. The analysis includes gate driver circuit implementation, snubber circuit design for voltage spike suppression, and feedback control algorithms for output voltage regulation. Through this introduction and analysis, readers can gain deeper understanding of the principles and applications of three-phase fully-controlled rectifier bridges, as well as methodologies for designing and optimizing such circuits, including parameter tuning techniques and thermal management considerations for IGBT devices.
