Design and self-calibration of cascaded inductive voltage divider with ratio of 2n:1

Abstract

A set of cascaded IVDs with ratio of 2n:1 has been designed and self-calibrated. The IVD is built based on the use of the cascaded structure between the IVD with ratio of 2n-1:1 and BIVD. The amplitude errors and phase angle errors of the IVDs with ratios from 2:1 to 256:1 have been measured by means of sampling method at frequencies ranging from 10 kHz to 100 kHz, and the measurement results are presented.
