Summary:
Common-mode voltage and current measurements are one of the key issues to solve EMC troubles in the field. Thus, there are several measurement probes have been developed to measure common-mode voltage and current of an electromagnetic disturbance [1]-[4]. However, only separately measuring voltage or current may lead overestimation or under-estimation of phenomena, because voltage and current depend on an impedance. This paper proposes novel non-invasive probe for measuring voltage and current of the electromagnetic disturbance, simultaneously. First, we show configuration of the new probe and describe its principle. Second, characteristics of the probe are presented and evaluated by comparing calculation from equivalent circuit. Finally, we show measured result of impulsive waveform in time domain.
