摘要

In order to solve the output signal matching problem of broadband voltage transformers, this paper designs a broadband voltage transformation unit based on zero pole feedback, which can achieve input signal inversion and 1:10 arbitrary ratio boosting function. Error analysis and testing are carried out on the broadband voltage transformation unit, and the output errors are respectively 42ppm and 24urad at any ratio of 1:1–1:10 boosting. The voltage transformation unit designed is beneficial for the development of wideband voltage sensors and is of great significance for the measurement of wide dynamic signals in new power systems.
