MATLAB Simulation Program for Three-Phase Active Power Filter (APF)

This self-developed MATLAB simulation program (compatible with MATLAB 2006a) for three-phase active power filters (APF) implements a control system with excellent filtering capabilities, making it suitable for reference in APF research and design. The program simulates and evaluates the performance of active power filters in three-phase power systems, providing comprehensive parameters and configuration options for customizing filter characteristics. Key implementation features include: - Instantaneous power theory (p-q theory) based harmonic detection algorithm - Space Vector PWM (SVPWM) control technique for inverter switching - DC-link voltage regulation and current tracking control loops - Real-time compensation current generation with hysteresis band control Researchers can use this program to gain deep insights into APF operational principles and advantages, while obtaining practical guidance for designing and optimizing APF systems through modifiable simulation parameters and visualized performance metrics.
