Abstract

Electromagnetic compatibility is one of the major issues regarding high-voltage networks in hybrid or electric vehicles. In order to be able to accurately localize the sources of electromagnetic interference, it is necessary to directly measure the high-frequency, transient currents and voltages on the high-voltage cables below the screen. Hence, this paper presents a novel measurement system, consisting of directional couplers and a time domain measurement method with previous calibration of the couplers in the frequency domain. This system is able to perform the aforementioned task in the frequency range from 150 kHz to 1 GHz with negligible influence on the high-voltage network itself. It was already verified by measurements conducted in an electric vehicle.
