Hello Sai,

    1). Ferrite core

     The loss tangent is only for hystersis loss, not for eddy current. You can enable eddy effect and enter conductivity in solid core materail, when the material is not lamination. After inceasing peak current, you may need to change the loss tangent value. However, you could select hystersis loss model to calculate hysteresis loss, and use eddy effect and conductivity to calculate eddy current loss. 

     2). Lamination

     If the materail is the lamination, you need to use electrical steel in core loss model. With the very high frequency, the coeffiient of the eddy current loss is very important. You have to have measured loss data for the core loss calculation, or estimate skin effect on the eddy current of the lamination.
