GBP Four Quadrant Medium Voltage VFD

GBP3-H Series Medium Voltage VFD for Mine Hoist
 

Principle of GBP-H Four Quadrant Medium Voltage VFD

GBP3-H Four Quadrant Medium Voltage Variable Frequency Drive is a special Medium Voltage Variable-Frequency Drive independently developed and produced by our company according to the operation requirements of mine hoist.This drive is based on the technology of series power unit and stack wave, high performance vector control technology as the core. This drive consists of rectifier phase shifting transformer, power unit and control part.
The output voltage range from 3 KV to 10 KV, different output voltage with different number of power units, 3 KV has 9 power units, 6 KV has 15 power units, 10 KV has 24 power units and the power units on each phase are connected in series and stack wave to increase voltage. The power units on the three-phase are connected by Y type, outputting rated voltage directly.
