| Abstract: | Various configurations of average-sensing AC/DC converters for precision AC voltage measurements are described. Due to the unique electrical configurations in which the influence of the inaccuracy of ratio resistors is suppressed, these converters have high accuracy (better than 0.01%) and resolution (0.0001%) at medium frequencies. Their frequency range is from 10 Hz to 1 MHz, with a settling time less than 1 s |
