Fuzzy Controlled Shunt Active Power Filter for Line Harmonic Mitigation [PDF]
, 2014 - Epidemic applications of power electronic based non-linear loads result in increase of harmonics in the power system. The current harmonics produced by these non-linear loads result in voltage distortion and leads to various power quality problems.

IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.In this paper, a constrained FCS‐MPC based current controller is introduced for controlling shunt active power filters. In the proposed current controller, the objective function is same as used in the conventional FCS‐MPC and a switching frequency constraint is considered to reduce the average switching frequency. The results obtained from FPGA in the
