Applications
Medium-Voltage Inverters

Medium-Voltage Inverters
These units are used for inverter driving 3-phase AC 3 k/6 k/6.6 kV high-voltage motors in iron and steel plants, textile plants and paper mills.
We have developed a series of 1.7 kV and 3.3 kV high voltage IGBT modules for use with medium-voltage inverters.
