APF Simulation Waveforms Based on IP-IQ Instantaneous Power Theory

This article presents simulation waveforms of Active Power Filter (APF) based on IP-IQ instantaneous power theory, designed for three-phase three-wire power systems. The implementation typically involves MATLAB/Simulink modeling with key components including Clarke transformation (α-β coordinates) for voltage/current conversion, instantaneous power calculation blocks, and hysteresis current control for switching signals generation. For researchers requiring APF simulation waveforms under three-phase four-wire power systems, we can provide additional simulation results and corresponding control strategy implementations. Furthermore, this article details the working principle of APF and its applications in power systems, including harmonic detection algorithms using p-q theory and DC-link voltage regulation techniques, to enhance understanding of this technology and its advantages. The control algorithm typically features real-time harmonic compensation through instantaneous power calculation and proportional-integral (PI) controllers for maintaining DC capacitor voltage.
