Abstract：As part of hoist system in coal mine adopts full digital DC motor speed control devices, which may bring about harmonic wave and pollutes the coal mine grid. In order to solve this problem in the coal mine, four-wire system based on three-level four-leg topological structure was developed. The frequency dividing control algorithm was studied and specified subharmonic current compensation frequency dividing control technology was analyzed. At last, the system was verified through MATLAB simulation, and the control method was verified through experiment.
