Dynamic Properties of Very Thin 3% Si-Fe Cores in Relation to the Number of Layers


We previously reported that the estimated eddy current losses of very thin 3% Si-Fe strip-wound cores in the 500 Hz to 5 kHz frequency range agreed comparatively well with measured values. The eddy current losses were estimated by employing the number of domain walls in a modified Pry and Bean model. We observed the number of domain walis on outermost… (More)
