Embodiment 1
[0019] Embodiment one: see figure 2 , image 3 As shown, a dual-channel current sensor structure based on magnetic field detection includes two symmetrically arranged conductors 20 and 24, the conductors 20 and 24 themselves are symmetrical structures, and the U-shaped groove opening inside a conductor 20 is vertically mapped to A first inner Hall device 21 is arranged at the upper position, and two first outer Hall devices 22 and 23 are arranged at the position where the outer side is vertically mapped to the upper position, and the first outer Hall devices 22 and 23 are arranged on the line of symmetry of the conductor 20 itself. Symmetrically arranged, a second inner Hall device 25 is arranged in the opening of the U-shaped groove inside the other conductor 24, which is vertically mapped to the upper layer, and two second outer Hall devices 26 are arranged at the position where the outer side is vertically mapped to the upper layer and 27, the straight-line distances from...
