Hi, <\/p>\n

I am simulating the small signal impedance response of custom fabricated toroid by experimentally measuring the permeability and loss tangent sweep at 1MHz to 1GHz. Since I am not using BP curves, I am not getting core loss as-is in the solution data. But fundamentally, loss tangent should also contain a little bit of eddy and hysteresis information. <\/p>\n

Regardless when I calculate EM losses, my values are high (6W) when they are supposed to be in mW. My question is:<\/p>\n

    \n
  1. What is the formula in fields calculator for getting my eddy and hysteresis losses of the core? Is it possible to separate them?<\/li>\n
  2. Since these are R&D toroids custom-made at our facility, what other properties (like conductivity\/resistivty of core, mass\/density of core) is vital for loss calculations?<\/li>\n
  3. If I increase my peak AC current excitation to a relatively large signal (say from 1mA to 200 mA), is there a way to ask Ansys to proportionally increase the loss tangent so as to account for higher core losses due to higher pk-pk AC excitation strengths? (Excitation by impdance analyzers are less than 10 mT, so unless I have a BP curve, core loss at higher excitation window (+\/- Hm) seems impossible). <\/li>\n<\/ol>\n

    Thanks for your time. Please feel free to comment even if you don’t have the answer to all the questions. <\/p>\n
