Analysis of Ferrite Orthogonal-Core for High Frequency Region Based on Three-Dimensional Nonlinear Magnetic Circuit

Abstract

This paper presents an operating analysis of ferrite orthogonal-core for high frequency power control and power conversion. The analysis is based on the three-dimensional magnetic circuit of the orthogonal-core, and is called reluctance network analysis. The magnetization characteristics of the ferrite orthogonal-core are calculated accurately by using the reluctance network analysis. On the basis of the obtained magnetization curves, we can analyze the operating characteristics of the various application circuits of the orthogonal-core. For an example, the control characteristics of high frequency variable inductor using the ferrite orthogonal-core are calculated in this paper.
