Three-Phase SPWM Rectifier Circuit Simulink Simulation Source Code

In this documentation, I provide detailed information about the original Simulink simulation source code for a three-phase SPWM rectifier circuit. First, let's understand what a three-phase SPWM rectifier circuit is. It's a circuit designed to convert alternating current (AC) to direct current (DC), employing Space Vector Pulse Width Modulation (SPWM) technology to achieve precise control over the output voltage. The Simulink simulation source code serves as a powerful tool for modeling and validating circuit designs, enabling us to better comprehend the performance characteristics and operational behavior of three-phase SPWM rectifier circuits. The implementation includes key components such as PWM signal generation blocks, three-phase bridge rectifier configurations, and voltage/current measurement subsystems. The code utilizes MATLAB function blocks to implement SPWM algorithms that calculate proper switching sequences for the power electronic devices. Critical simulation parameters include carrier frequency settings, modulation index control, and load characteristics configuration. Now, I will demonstrate the specific implementation details of the Simulink simulation source code for the three-phase SPWM rectifier circuit, discussing its key features such as harmonic analysis capabilities, real-time waveform monitoring, and dynamic response testing. The application areas cover industrial power systems, renewable energy integration, and motor drive systems where efficient AC-DC conversion with minimal harmonic distortion is required.
