This paper proposes a novel method for current measurement using dual-Wheatstone bridge differential mode current. Compared with existing non-contact current detection systems, the proposed method is robust against inference, reliable, easy to be repackaged and applied at board-level, low-cost, and with a wide measuring range and low temperature drift. The article also illustrates the design and structure of the system, analyzes the working principle, and verifies the reliability and stability of the method by experimental data.
