Prime Soft family
Freewheeling diodes for medium voltage drives
The ultra-soft freewheeling diodes for IGBTs built on our existing IGCT freewheeling diode family. A very big improvement is the turn-off capability, which has been upgraded to 5 kA/us. These diodes are the perfect fit for modern IGBT applications such as HVDC voltage source converters and medium voltage drives.
This results in benefits such as a simplified mechanical stack construction with series stacking of press-pack IGBTs and freewheeling diodes. In addition, a time saving of 50% in stack design, fewer safety devices required thanks to high overload capability and an ideal applicability for building of gigawatt HVDC installations with low power losses.
