To reduce carbon dioxide emissions, it is important to conserve energy and promote the spread and expansion of renewable energy. Therefore, it is important to improve the efficiency of electromagnetic transformers. Transformers have been designed to reduce losses by using high-performance materials such as amorphous alloys and by optimizing the winging design, but little consideration has been given to reducing losses by optimizing the geometry of the iron core. First, a linear analysis is performed using the finite element method, taking magnetic anisotropy into account. Then, nonlinear analysis is performed using the newton-raphson method. Therefore, I propose a nonlinear analysis that takes magnetic anisotropy into account. Since two-dimensional magnetic characteristics are taken into account, more accurate analysis is possible, and the analysis is also useful for other electromagnetic devices. In this paper, I compare and discuss the calculation accuracy and speed.
