A GENERALIZED DYNAMIC CIRCUIT MODEL OF MAGNETIC CORES FOR LOW-FREQUENCY AND HIGH-FREQUENCY APPLICATIONS .1. THEORETICAL CALCULATION OF THE EQUIVALENT CORE LOSS RESISTANCE

This paper describes the theoretical calculation of the equivalent cor e loss resistance for a dynamic magnetic core loss model, The equivale nt core loss resistance incorporates the effects of both the classical eddy current and anomalous losses, Derivation of a generalized nonlin ear core loss resistance expression is presented. This new equivalent core loss resistance can be incorporated into a generalized dynamic ma gnetic core circuit model suitable for low and high frequency applicat ions (Part II of this paper).
