Magnetic field analysis of amorphous core transformer using homogenization technique

Abstract

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 analyze a joint part of amorphous core transformer microscopically. A butt-iap-step joint type of lamination method is modeled and its equivalent reluctivity is calculated to analyze various quantities of the magnetic fields.
