Abstract
Magnetic circuit methods make it possible to analyze characteristics of various magnetic devices by simple calculations. Furthermore, we can use general-purpose tools, such as a SPICE circuit simulator, for calculation. In a previous paper, we proposed a method for calculating iron loss characteristics based on a magnetic circuit model considering iron loss. However, since this method treats hysteresis loss and eddy-current loss collectively, it is necessary to vary the parameters of the magnetic circuit model when frequency is varied. In this paper, we propose a method for calculating iron loss for each frequency without varying the parameters of the magnetic circuit.
