In this paper, we propose a new approach for designing a high performance and low-cost sensor array based current transducer. This is based on the use of tunnel magnetoresistive sensor array and adaptive blind source separation method. Such a sensor array is able to cancel magnetic interference from nearby current carrying conductors by giving a near perfect estimation and separation of the unknown source signals. Experiment using a hardware prototype based on an analog interface and a DSP for enhancing flexibility was used. The result obtained with the used of Tunnel Magnetoresistive sensor array is presented in this paper.
