近来，由于对SiC功率器件的研究和开发，已经提出了诸如使用中频（MF）变压器的高功率隔离DC-DC转换器（双有源桥）的功率转换器电路。转换器电路需要MF Transformer和电感器，但这些磁性元件在电路体积中占主导地位。为了实现高功率密度的隔离式DC-DC变换器，有必要对中频Transformer和电感中的损耗进行分析。提出了一种基于改进的广义斯坦梅茨方程（iGSE）的铁损计算方法。为了对铁耗进行详细分析，提出了将铁耗分为磁滞损耗和涡流损耗的分析方法。此外，本文提出了一个损耗分离的过程中的MF Transformer和电感的铁损。在该分析中，针对DC-DC转换器的不同操作模式执行铁损分析。最后，分析和实验结果证实了分离过程的有效性。
Recently, because of research and development into SiC power devices, power converter circuits such as high-power isolated DC-DC converters (dual active bridge) using medium-frequency (MF) transformers have been proposed. The converter circuit requires the MF transformer and inductors, but these magnetic components dominate the volume of the circuit. To realize a high-power-density isolated DC-DC converter, it is necessary to analyze the losses in the MF transformer and inductors. In this paper, an iron loss calculation method based on the improved generalized Steinmetz equation (iGSE) is presented. To analyze the iron loss in detail, an analysis method which divides the iron loss into the hysteresis loss and the eddy-current loss is also presented. Further, this paper presents a loss separation procedure for the iron loss in the MF transformer and inductors. In this analysis, the iron loss analysis is performed for different operation modes of the DC-DC converter. Finally, the validity of the separation procedure is confirmed by both analytical and experimental results.
