摘要

本文对环形磁芯虚隙技术进行了分析和展示。我们研究了环形磁芯中虚隙的影响。通过非线性有限元模拟,研究了虚隙对环形磁芯的影响。我们实现了几个分析磁静电(仅使用直流电流)。通过有限元仿真,揭示了环形磁芯中虚拟间隙的作用,以及该技术如何控制环形磁芯的磁化特性。此外,我们还提出了一种利用相同环形磁芯中存在虚拟气隙的结果来估计等效气隙的方法。此外,我们还展示了虚拟间隙如何控制环形磁芯的磁化曲线特性,从而改变孔绕组中的直流电流强度,以及我们如何以相同的方式改变饱和程度和虚拟间隙的大小。

Control of the Magnetizing Characteristics of a Toroidal Core Using Virtual Gap
A study of the technology of the virtual gap in a toroidal core is analyzed and showed in this paper. We made a study about of the effects of a virtual gap in a toroidal core. Through nonlinear finite element simulations we studied the effects that a virtual gap has on a toroidal core. We realized several analysis magnetic static (using only DC currents). The finite element simulations show the function of a virtual gap in a toroidal core and how this technology can help to control the magnetizing characteristics of a toroidal core. Furthermore, we proposed a method to estimate the equivalent air gap using the results obtained with a virtual gap in the same toroidal core. Moreover, we show how a virtual gap can control the characteristics of the magnetizing curve of a toroidal core varying the DC current intensity in the windings of the holes and how we can vary the saturation degree and the size of the virtual gap of the same manner.
