Why Litz Wire Is Adopted in Solid-State Transformers (SST)

Huayang Group Start to product Litz Wire 

 

Brief Summary of Key Reasons

 

1. Counteract skin effect via ultra-fine insulated strands;
2. Suppress proximity effect via periodic strand transposition;
3. Minimize high-frequency AC winding loss and raise SST conversion efficiency;
4. Reduce winding temperature rise and support high power density compact design;
5. Flexible structure for tight winding, compatible with SST high-temperature insulation systems;
6. Reliable equal current sharing for high-current low-voltage windings of medium-frequency SST.
