The methods of speed control for a traditional electric locomotive are series resistance and DC chop- per PWM in a coal mine, but there are many disadvantages. The key problems about Electric locomotive using in a mine are that the power voltage fluctuation range is width and that bow is out of the overhead line fre- quently. In order to solve these disadvantages and these key problems, a DC-AC converter speed control sys- tem for a mining electric locomotive was designed, based on the vector control technology and space vector pulse width modulation (SVPWM) technology and using TMS320LF2407A DSP as a control core. A speed, current, position three closed-loop high performance speed control is realized. After testing in laboratory and using in coal mines, data analysis results Show that the DC-AC converter has a good and stability performance, the maintenance workload is significantly reduced and reliability meets harsh environment requirements com- pletely. The problems of a traditional mining electric locomotive are solved preferably.
