Abstract

There is an important significance of AC/DC comparator with high precision for the precision measurement in electric power industry. An AC/DC comparator based on the non integer period Sampling and rapid data refactoring is designed. The AC/DC comparator consists of the input buffer A/D change DC reference standard magnetic isolation and sampling control chip. AC/DC comparator is used to sample the AC Magnitude and realize the AC traceable to DC with the reference of the high precision DC reference standard. Through the error analysis of the AC/DC comparator for each part the Maximum error of voltage amplitude measurement is ±8×10-6.The experimental results show that the accuracy of frequency amplitude and phase is respectively 10-6 10-6 10-5 and the stability is 10-6 10-6 10-5. It proves that the AC/DC comparator can accurate measurement the fundamental magnitude of AC.
