In a design of electric devices, it is important to know the relation of the magnetic properties between the raw materials and the core. This paper describes the magnetic properties of tape wound ring core considering the influence of magnetization conditions and dimension ratio under ac excitation. In the analysis, magnetization characteristics are approximated by a Fourier series, and it is assumed that the eddy current factor is proportional to the rate of change of the flux. From the result of numerical analysis, the influences of oprating flux density, frequency, wave forms of input voltage on the relation between dimension ratio and ac magnetic properties are shown. The results of the analysis were confirmed by the experiments.
