High frequency inductor proximity loss calculation with 3D finite element analysis considering non-sinusoidal current distortion

This paper describes a 3D finite element (FE) based method to calculate the proximity losses for magnetic components in power conversion system. The proximity loss is the main concern of copper loss which causes ac losses in the winding. The FE model is built based on the definitions of the geometri...
