基于回转器-电容模型的变压器漏感的研究

摘要

回转器-电容模型是一种较新的描述磁性元件的电路模型.本文根据能量相等的基本原理推导变压器漏感在回转器-电容模型中的表现形式.文中具体给出了几种典型变压器的漏感能量求法,并对应回转器-电容模型给出了表征漏磁通的漏磁导电容值的求法；讨论了变压器绕组采用交错换位绕法后漏磁通发生的变化.通过一个立式变压器、平面变压器验证了漏磁导电容计算方法的有效性.%The gyrator-capacitor model is one of the preferable models for magnetic components. The representation of the transformer' s leakage inductance in gyrator-capacitor model based on the principle of energy equality is given in this paper. The calculation methods of the equivalent leakage permeance capacitor of different types of transform ers are presented in the paper. Besides, the calculation method of the permeance capacitor of interleaved windings transformer is also presented in this paper. The experimental results verify the validity of the proposed method.
