Comparison of Sinusoidal Current Control Strategy & Synchronous Rotating Frame Strategy for Total Harmonic Reduction for Power Electronic Converters in Aircraft System under Different Load Conditions

[摘要] Two dissimilar control strategies for extracting reference currents for shunt active power filters have been evaluated and their performances have been compared under various non linear loads. Comparison of the compensation ability of different control strategies based on THD and speed will be done and suggestions will be given for the selection of strategy to be used under different load. The simulated results using MATLAB model are presented and they will clearly prove the effectiveness of the proposed control method of aircraft shunt APF.
