Estimating the core losses of magnetic materials is crucial for the electrical, thermal, and mechanical modeling of modern power electronic converters. Thus, there have been a number of methods proposed in the literature to estimate core losses. However, none of the existing works have introduced a method to estimate the core losses for arbitrary flux density waveforms by making use of manufacturer provided loss calculation parameters with a memory efficient algorithm. In this paper, existing core loss estimation methods are reviewed and a novel method is proposed to estimate the core losses under arbitrary voltage excitation by a modification of the improved Generalized Steinmetz Equation (iGSE) algorithm. The novel method is referred to as the Recursive Improved Generalized Steinmetz Equation (RiGSE) and its performance is experimentally verified for arbitrary flux density waveforms. The experimental verification of the proposed core loss estimating method is the only known example in the existing literature in terms of the evaluation of arbitrary flux density waveforms.

估计磁性材料的磁芯损耗对于现代电力电子转换器的电气、热和机械建模至关重要。因此，文献中提出了许多方法来估计铁芯损耗。然而，现有的工作都没有引入一种方法来估计任意磁通密度波形的磁芯损耗，方法是利用制造商提供的损耗计算参数和内存高效算法。本文回顾了现有的铁损估计方法，提出了一种通过改进广义斯坦梅茨方程（iGSE）算法来估计任意电压激励下铁损的新方法。这种新方法被称为递归改进广义 Steinmetz 方程 (RiGSE)，其性能已针对任意磁通密度波形进行了实验验证。在评估任意磁通密度波形方面，所提出的铁损估计方法的实验验证是现有文献中唯一已知的例子。
