摘要

在现在和未来的乘用车中，安装越来越多的电气和电子设备是一种趋势。一些新系统，如主动车身控制系统、电动制动系统和其他大功率设备，对电力的需求越来越大。在这种器件的开关过程中会出现高电流和电压峰值，并伴有相应的扰动。为了更好地了解快速瞬变及其在线束上的传播，开发了一种新的测量系统。该系统必须涵盖汽车领域的几个要求。它必须能够承受高场强的抗扰度测试，并且不得影响汽车的电气和电子设备的测量和功能。因此，使用了几种具有光学数据链路的无电位电压探头。整个系统由电池供电，体积小，适合移动使用。

A new test system for measurements of fast transients in passenger cars

In present and future passenger cars there is a trend to install more and more electric and electronic devices. Some of the new systems like active body control, electric brake systems and other high power devices have an increasing demand for electric power. High current and voltage peaks with corresponding disturbance can occur during switching of such devices. A new measuring system has been developed to get a better overview of the fast transients and their propagation on the wiring harness. There are several requirements in the automotive area the system has to cover. It must be able to withstand the immunity test with high field strengths and must not influence the measurements and the function of the electric and electronic devices of the car. Therefore several potential free voltage probes with optical data links are used. The whole system is battery supplied and of small size to be suitable for mobile use.
