Abstract
A new type of AC current shunt for AC-DC current transfer is presented for which the AC-DC current differences at frequencies from 10 to 100 kHz are calculated with uncertainties smaller than plusmn 9 muA/A in the current range of 30 mA-10 A. This is an independent realization of the AC-DC current-transfer standards in addition to the step-up method used at most National Metrology Institutes. The construction, modeling, and experimental verification of the shunts are described.
