Wide band measurement of precision magnetic potentiometer with proportion-integral-differentiator for heavy pulse current

Abstract

A wide band measurement system of magnetic potentiometer of high precision with proportion-integral-differentiator for heavy pulse and alternating current is developed. The experiment results show that the new measurement system achieves band spread from 8 kHz to 70 kHz. The band of new measurement system is about 10 times wider than a conventional measurement system. The design and calculations of the new measurement system are given.
