基于碳化硅和氮化镓等宽带隙半导体的下一代功率器件的开关速度比传统的硅绝缘栅双极晶体管快十倍以上。这可能增加伴随功率转换器的开关操作的电磁噪声的频率范围。此外，由于磁性材料的频率依赖性和无源部件的寄生部件，噪声滤波器的工作频率范围受到限制，因此，难以实现工作频率范围超过几十兆赫的高频（HF）噪声滤波器。本文提出了一种估计高频三相共模电感工作频率范围的建模技术。所提出的方法包括一种新的简单的估计技术的绕组杂散电容。CM阻抗测量结果验证了所提出的模型可以估计高频三相CM电感器的工作频率范围，同时在设计阶段确保实际足够的精度。
Switching speed of the next-generation power devices based on the wide-bandgap semiconductors such as silicon carbide and gallium nitride are more than ten times faster than the conventional silicon insulated-gate bipolar transistors. This may increase frequency ranges of electromagnetic noise accompanied by switching operations of power converters. Besides, the operating frequency ranges of noise filters are limited due to frequency dependencies of magnetic materials and parasitic components of passive components, thus, the realization of the high-frequency (HF) noise filter with the operating frequency range beyond several ten megahertz is difficult. This paper presents a modeling technique for estimating the operating frequency range of the HF three-phase common-mode (CM) inductors. The proposed method includes a novel simple estimation technique of winding stray capacitance. The CM impedance measurement results validate that the proposing model can estimate the operating frequency range of the HF three-phase CM inductor while securing practically sufficient precision at the design-stage.
