Whitepaper - Measurement of Loss in High-Frequency Reactors

White paper / Application

Power analyzer measures reactor Total loss and Core loss

Why Should Reactor Loss be Analyzed?
By directly measuring reactor loss, as well as iron loss and copper loss ratios within reactor loss, you can
significantly reduce research and development time and identify areas of improvement for reaching even
higher efficiency and smaller form factors.

  • High iron loss -> Issues with the core likely; focus on improving the structure and materials.
  • High copper loss -> Issues with the winding coil likely; focus on improving the winding method or materials.
