Abstract

An intelligent AC/DC voltage standard has been constructed to meet stringent demands for calibration in laboratories as well as in demanding industrial environments. The use of a microcomputer MC enables programmable output parameters, storage of calibration constants, and integration into a complex measuring and testing system. Stability of AC and DC parameters, reliability of operation, and reliability of metrological parameters were achieved by real-time data processing. The prototype exhibited the following characteristics: an output frequency range from 30 to 400 Hz with a resolution of 1 Hz, four voltage ranges from 0.1 to 1000 V with 12-bit resolution, and output power of 50 V·A with limitations of output voltage U_max=1000 V_RMS and output current I _max=5 A_RMS
