本文讨论了虚拟气隙(VAG)函数的解析模型，以确定该技术在复杂器件中使用时的设计规则。这些设计规则的建立构成了本文提出的关于单相磁芯的开发的主要原创性。它基于非线性磁阻网络的定义，该网络同时考虑了包含VAG的扰动区域中的直流和交流磁通分量的影响。通过有限元分析和实验对计算结果进行了验证。
This paper deals with an analytical model of the virtual air gap (VAG) function in order to define design rules when this technique is used inside complex devices. The establishment of those design rules constitutes the main originality of the developments presented in this paper, which are about a single-phase magnetic core. It is based on the definition of a nonlinear reluctance network that takes simultaneously into account the effects of dc and ac magnetic flux components in the disturbed area that contains the VAG. The results are validated using a finite-element analysis and experimentally.
