What are the requirements for magnetic materials used in high frequency to reduce what?
The hysteresis and eddy current losses of magnetic materials are related to the operating frequency f and the work flux density Bm.
The elevation of f or Bm increases, the loss will be greatly increased, resulting in the magnetic material of severe fever, which requires the resistivity of the magnetic material P to be big, in order to effectively suppress eddy current loss.
In order to improve the magnetic density Bm, the saturation flux density of the material is higher than that of Bs. In order to make the magnetic component have good working characteristics in a relatively wide temperature range, the Curie temperature Tc requirement of the magnetic material is relatively high. The loss of magnetic material as transmission power should be very low.
