Relevant technical study on resonant impedance type active power filter（ RITHAPF） is carried out for the harmonic mitigation and reactive power compensation of a 6 k V mine hoisting system. The structure and mathematical model of RITHAPF is analyzed. A discrete decoupling mathematical model for two-level APF is constructed and the current tracking controller is devised based on discrete SMC. Systematical simulation results demonstrate that the proposed RITHAPF is capable of compensating harmonics and reactive power for the 6 k V hoisting system and effectively suppresses the hoist start overshoot.
