Abstract
An adaptive active power filter (APF) for the DC grid in ships is proposed to suppress harmonic currents above kilohertz. The delay notch Filtered X-Least Mean Square (FXLMS) algorithm is introduced as the control algorithm of adaptive APF in this paper. Taking the typical twelve-pulse rectifier device of DC grid in ships as an example, a MATLAB / Simulink simulation model of APF based on both delay notch FXLMS algorithm and classical FXLMS algorithm are built, and the calculation amount of the two algorithms is compared. The harmonic suppression effect of delay notch FXLMS algorithm in the situation that harmonic source changes dynamically is also simulated.
