This paper presents innovative isolated DC and AC current amplifier containing magnetic field sensor in the feedback loop. The amorphous ring core with an air gap is utilized as a part of the galvanic isolation separating input and output currents. In the paper outline of the amplifier is presented. The printed circuit board project was developed and electronic circuit of the amplifier was manufactured. The developed device was investigated with DC and AC current and the results are presented in the paper. Results indicate usefulness of the developed device in described application.
