XGap Technology
Xgap technology is a multi-gap core approach for transformers and inductors developed in-house to reduce AC losses in the windings that allows for the creation of cost-effective solutions for maximum power densities.
What is Xgap Technology?
- The multi-gap technology has been developed by PRAX to reduce winding AC losses.
- It allows to use big gaps distributed around the toroid to minimize fringing effect.
- It consists on splitting a big gap into smaller gaps. These smaller gaps are distributed around the toroidal core.
- Losses are reduced exponentially when we use up to 12-15 smaller gaps because of Rac reduction.
Advantages of Xgap Technology
- Gap distributed component, minimizing fringing losses.
- Increases winding area by using toroid formats. Not needed to keep windings far away from the gap.
- High current and high frequencies handling by means of using low losses ferrite material
- Best dissipation of windings in any type of cooling systems
- Tighter tolerances for the inductance value (from ±25% to ±10%)
- Reduction of core volume around 30%, allowing an overall size reduction of around 15-20% Cost-effective solution (i.e. compared with PQ or PM format)
