本文論述了高速計算机的电源分配問題,对电源电压静态偏差問题未加討論。从一般电感的角度出发,分析了电源分配的最佳方法。其結論是采用平面导线的平衡传輸线。分析結果設計出了每英尺的电感小于30微微亨的电源傳輸线。本文指出不仅需要减小传輸线的电感,而且还要求频带寬和特性阻抗低。其次,提出接上外部电容有助于减小在电源导线上的,以及插件板内和插件板之間的干扰。而且分析了振盪問题和傳输线的終端配接問题。概述了测量傳輸线特性的脉冲方法。
This article discusses the high-speed computer power distribution problems, the static power supply voltage deviation is not discussed. From the perspective of the general inductance, the best way to distribute power is analyzed. The conclusion is that the use of flat wire balanced transmission line. The results of the analysis devised a power transmission line with an inductance of less than 30 μF per foot. This paper points out not only the need to reduce the inductance of the transmission line but also the low bandwidth and low characteristic impedance. Second, it is proposed to connect an external capacitor to help reduce the wiring on the power supply and between the board and the board. But also analyzed the oscillation problem and the transmission line termination problem. An overview of the pulse measurement method of measuring the characteristics of the transmission line.
