Research on Mine Frequency Converter Mutual Feedback Experimental Device

Abstract

Aiming at the problems that are difficult to realize in the test, troubleshooting and maintenance of high-power inverter performance and function in mining, especially the difficulty of power experiment, a high-power experimental device is proposed. The hardware circuit of the system is given based on TMS320F28335. The software implementation scheme and circuit structure adopt vector control strategy to realize closed-loop control of speed and torque. Field experiment debugging verified the feasibility and correctness of the mutual feedback experimental device, which can be promoted and applied in the coal mining industry.
