Characterizing Magnetic Components

Partner Call open until: 30.12.19

Start (of the project): Q1 2020

Objectives

The goal of the project is to characterize and model ferrite foils for wireless power transfer systems at  13.56MHz. This knowledge allows a simplified design process and shorter development times.

The goal of the project is to simplify the design process of wireless power transfer systems. To avoid high stray magnetic fields of the loosely coupled energy transfer systems, ferrite foils are used to guide the field lines. The characteristics of the ferrite foils include nonlinear magnetization behavior, anisotropy, influence on the parameters due external magnetic fields, to name a few. The characteristics of the foils will be investigated and modeled in the frequency range of 13.56MHz. These models will allow improved design methods leading to shorter development times, as well as better use of the ferrite foils with shrinking size.

Expected results

  • Characterization of the ferrite foils
  • Knowledge on the characteristics of the ferrite foils in corner regions of the applications
  • Models of the ferrite foils for the usage in system simulations
  • Shorter development times for wireless power transfer systems
