SPWM激励下电感集成三相三维卷铁心变压器的建模与优化设计

Compared with the laminated core transformer, the three-dimensional (3-D) wound core transformer(3-D-WCT) has the characteristics of symmetrical magnetic circuit and low vibration. This article focuses on the modeling and optimal design of the 3-D-WCT for isolated dc/ac application. First, based on the Jiles–Aterton model, a nonlinear magnetic circuit model of the 3-D-WCT is established to calcula...
