    • Abstract
  • Hybrid power filter is consist of passive and active filters linked by different methods. In this paper, the configuration of hybrid filter suited to coal mines is selected by Characteritics of harmonic source in mine power network. A kind of method which calculates harmonic current using DSP with harmonic voltage detection is proposed and circuit mode is constituted by the method. Excellent harmonic suppression characteristics of the hybrid filter are shown by the simulation results, and the rationality of the design thought of the hybrid filter and the validity of the conclusions are proved.
