Iron loss analysis in wound core of reactor with gap considering skin effect

摘要

A wound core of reactor with the gap at high frequency is analyzed using the three-dimensional parallel finite element method. First of all, the effects of the mesh division of the steel sheet on the iron loss are clarified. After that, the effects of the frequency on the iron loss are clarified. Consequently, the iron loss of the reactor at the high frequency considering the skin effect is quantitatively clarified.
