A New Converter Used in Mine Hoist Speed Control

摘要

In light of the old mine hoist speed control system given vast pollution to the grid, used a new converter-two-stage matrix converter (TSMC) as the power converter to replace the traditional voltagetype inverter. The system not only makes it achieve Direct Torque Control (DTC), but also has many advantages of TSMC. TSMC and DTC's combination not only achieves a better transmission performance, but also meets increasingly stringent power quality requirements and achieves "green speed regulation."
