Power Quality Improvement Fuzzy Logical Controlled Based on Cascaded Shunt Active Power Filter

Improve its quality and reliability catches growing interest. In this paper, based on the analysis and modeling of the shunt APF with close-loop control, a feed forward compensation path of load current and also fuzzy logic control is applied to improve the dynamic performance of the APF.. The two H-bridge cascaded inverter is used for the aeronautical APF (AAPF). Justifications for topology choosing and corresponding system control method are given. Furthermore, the global framework and operation principle of the proposed AAPF are presented in detail. Simulated waveforms in different load conditions indicate the good performance of the AAPF.
