Resource Overview
An active power filter implementation using hysteresis-based control, developed on the MATLAB Simulink platform for power quality improvement and harmonic compensation applications.
Detailed Documentation
The active power filter is a functional power electronic device designed for harmonic suppression and reactive power compensation in electrical systems. This implementation utilizes hysteresis current control technology to achieve fast dynamic response and precise current tracking. The system is modeled and simulated on the MATLAB Simulink platform, featuring key components including the PWM signal generation module, current detection circuit, and hysteresis comparator implementation. The control algorithm continuously monitors load current harmonics and injects compensating currents through the IGBT-based inverter structure to maintain sinusoidal source currents.
