Development of An Algorithm to Analyse Magnetic Field of Amorphous Core using Homogenization Technique

균질화 기법을 이용한 비정질 Core의 자개해석 Algorithm개발

A solution of magnetic fields for amorphous core transformer has been tried using homogenization technique. The technique, which is derived by applying asymptotic expansion to the standard finite element method, is helpful to analyse a joint part of amorphous core transformer microscopically. A butt-lap-step joint type of lamination method is modeled and its equivalent reluctivity is calculated to analyse various quantities of the magnetic fields. The algorithm is also applicable to other electric devices which have complicated material structure with repeated patterns.
