摘要：

A planar current sensor, comprised of a magnetic current transformer and. a Hall-effect element, is presented. The sensor has a broad frequency bandwidth from de up to 30 MHz, a high current rating (40-A dc), superior linearity, high EMI immunity, small size, robustness, and low realization cost. The main design formulations are given analytically; simulations and finite-element results are presented for verification. Experimental results of current step response and dv / dt immunity are included.
