Abstract :
The assumption of equal current distribution in parallel windings of coils may lead to a wrong loss prediction. An analytical calculation of the current sharing, which is based on both the frequency dependent resistances of the parallel windings and on the magnetic coupling between these windings, is introduced and verified by measurements.
