摘要

辐射电磁干扰的主要来源之一是印刷电路板(PCB)中的电源总线谐振。将一种快速算法与分割法相结合，用于计算由矩形和直角三角形分段组成的电源母线的谐振特性。计算结果与实测结果吻合良好，证明了快速算法和分割方法的有效性和准确性。

Analysis of resonance characteristics of a power bus with rectangle and triangle elements in multilayer PCBs

One of the major sources of radiated EMI is attributed to power bus resonance in a printed circuit board (PCB). A fast algorithm, combined with the segmentation method, is applied for calculating resonance characteristics of a power bus whose pattern consists of several segments of rectangles and/or right-angled triangles. Good agreement between the calculated and measured results demonstrates the usefulness and accuracy of the fast algorithm and the segmentation method.
