摘要：
A fast switching system for AC-DC transfer difference measurements is presented in this paper. The paper describes assembling process of fast switching system. The system consists of control unit and relay box, in which relays are placed. Also, whole system is developed in-house for the purpose of AC-DC transfer difference measurement. This measurement is one parameter within characterization of nine shunts (cage type design) in range from 1 mA up to 10 A. This measurement includes using thermal converters. Since, it is substantial to apply ac, dc+ and dc-voltage without interruptions. That means switching time must be smaller than thermal time constant of the thermal converters.
