Driving Circuit Design of Three-level Inverter for Mining Transport Machine

Abstract

For the three-level inverter of mining, in order to improve the operating efficiency of the system and reduce the overshoot of current and voltage, and extend the life of the motor and inverter, the new high-voltage high-power IGBT drive module 2QD30A17K-I is used to design the drive circuit, analyzed the working principle of drive circuit, designed over-current, short circuit protection, and under-voltage protection circuit, gives the basic three-level drive circuit schematic diagram, parameter calculation and selection of components, experimental verification verifies the feasibility and correctness of the drive circuit, it can be promoted and applied in the coal mining industry.
