Abstract

Due to the large number of non-linear loads that are connected to the power system, the current power system is distorted and the operating efficiency is reduced. Given this situation, this study, is focused on the design of an active power filter based on fuzzy control technology. In this study, ic and dic/dt were used as the input part of the fuzzy control. After the fuzzy control, the main circuit driven by the PWM control signal is obtained and the closed-loop control system is formed. Simultaneously, MATLAB was used to model and simulate the fuzzy active power filter, and the correctness and feasibility of the improved system was verified by the comparison of simulation waveform diagrams and spectrogram results. The simulation results show that the active filter based on fuzzy control designed in this study effectively suppresses harmonics, and can be used as a valuable reference for subsequent research.
