複素透磁率を用いた高周波用変流器の動作解析

抄録

This paper describes an analysis concerning the characteristics of current transformers (CT), considering the dynamic hysteresis loops of magnetic core. This analysis is performed using complex permeability to express magnetic hysteresis. This method is applied to CT with radio-frequency currents for switching power supplies, and the calculated results are in very good agreenent with the experimental ones. This analytical method is available for calculating the ratio of transformation and the phase angle of CT, and is useful in the design of CT.
