摘要

—In the process of converter driving mine hoist, the output voltage waveform of the inverter is distorted. A novel feedback control method based on the filter inductor current inside loop and voltage is developed in this study. The transfer function model of the two closed-loop control is builded. Parameters of the PID controller are determined through theoretical calculation after analysis of the impact the controller parameters on system. The simulation results show that the output waveform is good and the THD(Total Harmonic Distortion) values is small.
