Abstract :
In this paper the electric and magnetic field distribution is investigated in solid toroidal cores with rectangular cross section. An analytical method is used in which the field distribution is calculated by means of orthogonal expansion. Based on the results, the influence of various parameters, such as frequency and conductivity of the core material, on the core losses is discussed. The calculated results are compared with measured data, a good agreement between the two values is achieved.
