Abstract

In this paper, we propose an electromagnetic and thermal coupled analysis of a ferrite orthogonal-core variable inductor based on the equivalent circuit theory. A three-dimensional reluctance network model and thermal-resistance network model are combined with each other, and calculated simultaneously on a general purpose circuit simulator SPICE.
