Abstract
A method of predicting the performance of certain electromagnetic devices is based on the integrated average core loss (IACL) and the integrated average relative permeability (IAP) of the electromagnetic core material used in the devices. The method includes the steps of establishing the range of induced magnetic fields over which the device is designed to operate, measuring the core loss and relative permeability of the core material over the range of induced fields and calculating the IACL and IAP over the range. Performance parameters can then be predicted using equations based on the IACL and the IAP with coefficients and constants derived through linear regression analysis.
