[New technical field] The creation system has a closed-loop current sensing device that is “small and small. The current is transmitted through the coil (primary side) to generate a magnetic field through the coil. The electromagnetic detection thousands converts the magnetic field into a voltage (millivolts mV), and then converts it into a current through an electronic circuit, and then flows the other coil of the ^^, lj electromagnetic material (primary side) and then receives the induced current through the signal output pin. j Use the miniaturization mechanism of this creation to reduce the cost of the application and use it more. [Previous Technology] • The conventional small current sensing device is shown in Figure 1 and Section 1. Brother 2 is not. The current shown in the figure causes the electromagnetic material 6 to generate a magnetic field through the coil 5. The permeate detecting element 3 converts the magnetic field into a millivolt mV, and then the voltage is amplified by the electronic circuit board 2 through the signal wheel. ▲Common current sensing "When a long time current flows through the coil 5, the electromagnetic material is loaded with a high magnetic flux. The electromagnetic material 6 _ production:, cake Yuan, θ ..., U 4 heat back to cause electromagnetic material产生 The magnetic field is cut, so the viciousness makes the current sense _ accuracy worse. :
