摘要：
A phase compensation method based on signal transfer principle of electronic transformer is presented. The causes of phase error in electronic transformer are analyzed. The phase-delay caused by Rogowski coil and time-delay in signal transferring process from high voltage side to merging unit are analyzed. A phase compensation method is proposed based on high sampling rate and linear interpolation. The simulation result verifies the effectiveness of the proposed compensation method for electronic transformers.
