Choke NTT LD-DH 100
Directly cooled surge current choke
Description
The current limiting inductor limits the short-circuit current in a bridge circuit. Thus, the intermediate circuit is protected and prevents the destruction of the connected semiconductor devices. Usually IGBT‘s.
Advantages
- Less copper
- Small dimensions compared to traditional cooling methods
- Lower weight
- Cooling with water/glycol
