XGap Technology

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)
