Abstract

Abstract: In order to accurately calculate the deducting transformer core loss, on the basis of analysis on traditional finite element method and Steinmetz method, an edge-nodal coupled $E-\psi$ method was proposed to calculate the High Power High Frequency High Voltage transformer core loss. Taking a 20 kHz, 50 kV, 60 kW transformer for example, the 3D model was established to calculate the transformer core loss. By comparing the measured data of transformer core loss with the figures calculated by edge-nodal coupled $E-\psi$ method, NFEM, EFEM and Steinmetz method, the comparison results show that: the edge-nodal coupled $E-\psi$ method has higher accuracy than results calculated by Steinmetz model, edge finite element method and node finite element method.
