提出了一种双惠斯通桥差模电路的磁阻传感器电流测量新方法。本方法采用通用低成本磁阻传感器，相对于目前主流的电流检测技术具有抗干扰能力强、可靠、易于实现二次封装与板级应用、性价比高、测量范围广、温度漂移低的优点。本文详细介绍了系统的设计思想与结构，分析了系统工作原理，并通过实验数据验证了该方法的可靠性和稳定性。%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.
