Abstract

This paper presents an operating analysis of a ferrite orthogonal core for high-frequency power control and power conversion. The analysis is based on the three-dimensional nonlinear 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 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 a high-frequency variable inductor using the ferrite orthogonal core are calculated in this paper.
