近年来，电感器和变压器已成为电力电子电路设计中越来越重要的因素，不仅因为它们的体积现在是这些电路中的主要方面，而且因为它们的损耗有时不能忽略。因此，人们对开发能够以高精度计算磁性元件的损耗的简单快速的方法非常感兴趣，从而支持磁性元件的设计。然而，计算间隙电感器的铁损需要大量的测量数据或/和复杂的电磁仿真。提出了一种基于损耗图法的间隙电感铁损计算方法。所提出的方法的一个优点是，间隙电感器的铁损可以准确地计算，而不需要复杂的仿真和更少的测量工作比现有的方法。实验验证了所提出的方法使用间隙电感与锰锌铁氧体和铁粉芯。
In recent years, inductors and transformers have become increasingly important factors in power electronics circuit design, not only because their volume is now a dominant aspect in these circuits, but also because their losses sometimes cannot be neglected. Therefore, there is much interest in the development of simple and quick methods capable of calculating the losses of magnetic components with high accuracy, and thus support the design of magnetic components. However, calculating the iron losses of gapped inductors requires much measurement data or/and complex electromagnetic simulations. This paper proposes a novel iron loss calculation method for gapped inductors, based on the loss-map method. An advantage of the proposed method is that the iron losses of gapped inductors can be calculated accurately without the need for complex simulations and with less measurement effort than the existing approaches. The proposed method is experimentally verified using gapped inductors with both MnZn ferrite and iron dust cores.
