Development of an effective evaluation system for the immunity of electro-magnetic equipments

本研究的目的是利用斯泰克传输线组合印制电路板来研制电流探头。虽然电流探头的一些电气特性很重要，但最重要的是输电线路的电气特性由电流传感器互连和被测互连组成。我们称这条传输线为“T型传输线”。为了构建一种可以矢量检测电流强度的电流探头，需要将“T型传输线”传输线的特性阻抗设计为50%。由于测试中的互连和电流传感器的互连是以平坦的互连构造的，因此电力线的分布在垂直方向上根据互连的宽度有很大的不同。因此，等效介电常数随垂直方向互连线宽度的不同而变化很大。今年，我们使其出现在…此外，还可以计算T型传输线的特性阻抗。为此，我们利用测量系统的特性阻抗来端接T型传输线的边缘，并在另一对端子上获得传输线频率的电压反射系数的最大值与绝对值。通过计算T型传输线的特性阻抗之比，可以得到真空中T型传输线的特性阻抗的严格解和等效介电常数。今年，研制了各种结构的T型传输线，并通过实验获得了特性阻抗。在本研究中，我们采用T型传输线来测量特性阻抗。由此可见，这种方法不受传输线形状的影响，并通过实验得到了TEM型传输线的特性阻抗。该方法将应用于多种测量。较少

The purpose of this study is to develop a current probe by the use of stoic transmission line combined PCB. While some electric features of the current probe is important, the most important thing is electric features of transmission line consist of interconnection for current sensor and interconnection under test. We call this transmission line "T-type transmission line". In order to construct a current probe that can be detected current intensity vectorially, we need to design that the characteristic impedance of the transmission line for "T-type transmission line" is 50_. Because of interconnection under test and interconnection of the current sensor are constructed with a flat interconnection, the distribution of an electric lines of force differ greatly according to the width of the interconnection in a vertical direction. Thus, equivalent dielectric constant changes greatly according to the width of the interconnection of vertical direction.In this year, we have made it appear th … More at characteristic impedance of the T-type transmission line can be calculated. For that purpose, we terminate edge of the T-type transmission line using the characteristic impedance of the measurement system and we obtain maximal value with absolute value of the voltage reflection coefficient for the frequency of transmission line in other pair terminal. The characteristic impedance for the T-type transmission line constructed in vacuum can be obtained strict solution and the equivalent dielectric constant can be obtained by calculating ratio of characteristic impedance for the T-type transmission line.In this year, various structural T-type transmission lines are manufactured and the characteristic impedance is obtained experimentally. In this study, we adopt T-type transmission line to measure the characteristic impedance. It follows from this that this way is not influenced by the shape of the transmission line and the characteristic impedance for the TEM-type transmission line is obtained experimentally. This method will be applied variety of measurement. Less
