摘要：

A formula for dynamic power loss taking into account the displacement current effect is introduced. The calculated results based on the formula and the variation of core parameters, i.e. frequency dependence of resistivity, permeability and permittivity, are discussed comparing with the observed ones from 10kHz to 10MHz. In this frequency range the resistivity has a dominant influence yet on the power loss than the other parameters.
