Abstract :
A mathematical homogenization technique is applied to the computation of eddy currents in strip-wound amorphous cores. The results are compared with a standard finite-element (FE) solution of a test problem. The method is applied to the analysis of an amorphous core in a frequency range up to 1 MHz, with main emphasis on energy loss prediction.
