Abstract :
An AC voltage standard has been developed for the 10 Hz-1 MHz frequency range with basic accuracy of 37.5 p.p.m. The standard is programmable and twice as accurate as current calibrators. Unique circuitry used to achieve fast response and high frequency, high voltage capability is described. The AC voltage standard incorporates a novel solid-state thermal converter which uses proprietary concepts to speed up AC-DC conversion while maintaining broad bandwidth and high frequency response. Design concepts which reduce maintenance cost, automate calibration, and simplify precise traceable AC voltage measurements are also provided
