摘要：

On the basis of the three-phase four-wire shunt active power filter (APF), this paper discusses the control system. In order to produce compensation current faster, it takes the fusion of FFT and p-q method to detect the harmonic current, and adopt dual-DSP hardware structure based on MCBSP to realize signal processing. At the same time, this paper presents a three- closed-loop control system to keep the accuracy. Then, we build some MATLAB models for the control system to verify the validity of this system. At last, we did an experiment to realize the communication between the dual-DSP. © 2015 SERSC.
