Abstract
In this paper a thermal power comparator based on the push-pull techniques of sum-and-difference circuit is proposed. The power measurement by mean of push-pull techniques can reduce an error of unidentical thermal converters, and an error for the deviation from the parabola characteristics of heaters in thermal converters. It is shown that the uncertainty of the comparator can be obtained better than 30 ppm in the input frequency range from 40 Hz up to 1 kHz.
