Experimental Evaluation of the Voltage/Current Conversion Factor of Transformer-Type AANs for 8-Wire Unscreened Balanced Pairs by Round Robin Test

This paper investigates the voltage/current conversion factor of transformer-type Asymmetric Artificial Networks (AANs) for unscreened balanced pairs, focusing on variations due to common mode impedance of the Equipment Under Test (EUT). The experimental results shows that the conversion factor remains stable at approximately 43.5 dB across different test sites, utilizing an enhanced transformer-type AAN. This stability is crucial for improving the reliability of conducted emission measurements in diverse environments. The findings emphasize the importance of consistent voltage/current conversion factors for accurate electromagnetic compatibility assessments.
