由铁心加工尺寸导出的整流变压器模型

Modeling of Rectifier Transformer Derived from Core Processing Size

铁心加工尺寸对磁性元件的设计起着至关重要的作用,现行基于外部轮廊尺寸的经典建模法难以得到精准结果,影响变压器设计。该文提出一种基于铁心实际加工尺寸,以铁心截面积和窗口面积为基本变量的数学模型,所得的变压器体积、表面积和质量等均直接反应着实际情况。该文所提数学模型中的铁心截面积和窗口面积等可作为决策变量直接用于后续多目标约束优化设计。

Theprocessingsizeof the core plays an important role in the designofmagneticcomponents.The current classical modeling method based on the external contour dimension is difficult to obtain accurate results,which affects the transformer design.In this paper,amathematical model based on theactual processing size of the core is proposed.Thevolume,surface area and massof the transformer obtained directly reflect the actual situation The core cross-sectional area and window area in the proposed mathematical model can be directly used as decision variables for subsequent multi-objective constrained optimization design.
