Abstract

Quantitative analysis of iron loss taking magnetic hysteresis behavior into account is essential to development of high-efficiency electric machines. In a previous article, a novel magnetic circuit model incorporating a play model was proposed. It was clear that the proposed model can calculate the hysteresis loop of the magnetic reactor with high accuracy and high speed. However, there is a possibility for further improvement in the calculation accuracy of the minor loop generated from carrier harmonics under PWM excitation because the influence of the skin effect cannot be considered. Therefore, this article describes that the Cauer's equivalent circuit theory, which can represent dynamic hysteresis characteristics considering the influence of the skin effect, is applied to the magnetic circuit model, and indicates the validity of the proposed method experimentally.
