Abstract

This paper presents a new improvement in the design of a fluxgate-based current transducer in order to reduce the power consumption of control electronics. The proposed improvement involves the replacement of the output linear amplifier of the transducer by a class H amplifier. The output amplifier is devoted to the magnetic flux compensation and generates the transducer output current, which is proportional to the current to be measured. In this way, it is possible to reduce significantly the power consumption of these current transducers without affecting their performance in terms of linearity, accuracy, and bandwidth.<br />Peer Reviewed<br />Postprint (author's final draft)
