） Abstract： Core of the new type power transformer, which has the function of DC bias suppression, is consist of silicon steel sheet and the two-phase coupled magnetic material
This paper establishes hysteresis model for two-phase coupled magnetic material and calculates the hysteresis characteristics and magnetization trajectory under changing magnetic field based on improved Preisach model theory
Relationship between hysteresis characteristics of two-phase coupled magnetic material and current value of DC bias is achieved, which enable the new type power transformer to suppress DC bias automatically
Calculation and experiment results prove the correctness of hysteresis model based on Preisach theory, which provides appropriate method for hysteresis characteristics study of transformer core and lays the foundation for extensive application the two-phase coupled magnetic material
Keywords： magnetic material
为变压器铁心磁特性计算提供了简单准确的方法
