Abstract

This paper proposes an improved method for calculating static capacitance between two conductors with circular cross-sections in inductor windings. It considers the effects of electric field coupling and energy distribution on static capacitance. In this paper, the capacitance between two conductors in inductor windings is calculated by the improved calculation method and finite-element method (FEM), respectively. The relative error of the improved calculation method is between 0.11% and 4.51% compared to the FEM. In order to verify the effectiveness of this method for inductor winding, the orthogonal stacking winding and staggered stacking winding are chosen as calculation examples to accurately predict the static capacitance of multi-layer circular-section induction coils. Finite element models for the two types of windings are built to determine the capacitances for our 3 × 3 array arrangement winding. The results show that the improved calculation method proposed in this paper highly conforms to FEM. Finally, we adopt an air-cored cylindrical inductor winding for experimental verification, and the improved calculation method is proved to be correct.

一种改进的电感绕组静态电容计算方法

本文提出了一种计算电感绕组中圆形截面导体间静电电容的改进方法。考虑了电场耦合和能量分布对静电电容的影响。本文分别采用改进的计算方法和有限元法计算了电感绕组中两导体之间的电容。与有限元方法相比，改进计算方法的相对误差在0.11% ~ 4.51%之间。为了验证该方法对电感绕组的有效性，以正交叠加绕组和交错叠加绕组为计算例，准确预测多层圆截面感应线圈的静态电容。建立了两种类型绕组的有限元模型，以确定我们的3 × 3阵列绕组的电容。结果表明，本文提出的改进计算方法与有限元法高度吻合。最后，我们采用空心圆柱电感绕组进行实验验证，证明了改进的计算方法是正确的。
