Abstract: The paper analyzed status and development process of DC and AC mine hoist control system at home and abroad. It emphatically introduced application of three frequency-conversion speed-regulation systems based on double three-level topology in control system of mine hoist, namely high-voltage frequency-conversion speed-regulation system at stator side, double three-level frequency-conversion speed-regulation system of synchronous motor and AC-DC-AC voltage type SVPWM frequency-conversion speed-regulation system with double three-level. And it indicated that AC-DC-AC voltage type frequency-conversion speed-regulation system has better energy-saving effect and is most suitable for control system of mine hoist.
