Characteristics Analysis of the Square Laminated Core under dc-biased Magnetization by the Fixed-point Harmonic-balanced FEM

Abstract

The ferromagnetic core of power transformer is susceptible to dc bias and has special nonlinear and hysteretic characteristics under dc-biased magnetization. The dc-biasing magnetization curve of a square laminated core (SLC) can be obtained by dc bias test. The harmonic-balanced finite-element method (HBFEM) combined with the fixed-point technique is used… (More)
