A Novel Modeling Technique via Coupled Magnetic Equivalent Circuit With Vector Hysteresis Characteristics of Laminated Steels

“…T HE design of compact and efficient electromagnetic devices with laminated steel requires an electromagnetic simulation model coupled with the nonlinear magnetic characteristics of the soft-magnetic material as the authors discussed in [1]. This is commonly achieved by coupling the finite element method (FEM) with a nonlinear solver based on the single-valued magnetization curve (SVC), i.e.…”

“…Later, the proposed approach is extended to a real application with a three-limbed transformer using multiple MEC elements under the current excitation with different excitation levels and frequencies. The authors recently compared both models with the SVC and VHM for a single MEC element in [1]. This paper is the extended version of the previous work, where the authors present the experimental verification of the proposed model using transient simulations of the analyzed transformer.…”
