Directly cooled inrush current choke
Description
The short-circuit current limiting choke is used to limit the short-circuit current in the event of a bridge short circuit. This protects the intermediate circuit and prevents the IGBT from being destroyed.
Advantages
- very little copper usage
- very small dimensions compared to the non-forced cooling version
- significantly lower weight
- to be cooled with water/glycol
- very high protection class
- also suitable for high pulse currents
