Abstract

In this paper, a new calibration method is proposed to fulfill the requirement of calibration of electronic transformer. At first, the fast measurement method of power frequency is presented. And then the principle of Quasi-synchronous DFT algorithm is introduced in order to satisfy the special requirement of fast harmonic analysis during the calibration of electronic transformer. Therefore the amplitude error and phase error of electronic transformer could be obtained based on this new calibration method. The performance of method is verified by simulation results.
