Open-circuit fault diagnosis method for switching tube of mine NPC three-level inverter

The inverter of the motor drive system in the mine hoist and belt conveyor mostly adopts neutral point clamped (NPC) three-level inverter. This inverter has a large number of switching tubes and high running frequency. Switching the working state of the switching tubes at high frequency in a short t...
