AB - A method of reactive I-U (current voltage) conversion of three-phase circuit based on Hall effect is proposed, that is, the method and implementation of reactive current measurement of three-phase circuit based on Hall effect. Using the basic theories of three-phase circuits, RLC series parallel circuits, and integrated operational amplifiers, draw a Hall effect I-U conversion circuit diagram, conduct mathematical modeling analysis, design unit circuits, and configure parameters. Under the action of Hall elements, the phase current flowing through the load is added to the DC reference voltage source signal, and the resulting DC signal is superimposed. The phase voltage at both ends of the load is controlled by an input protection and square wave amplification circuit, which controls the conduction and cutoff of the transistor and outputs a switching signal. Two sets of signals jointly drive the core amplifier and filtering circuit to achieve I-U conversion. Based on the phase relationship of output I-U or the value of power factor angle , determine the nature of the load, calculate the parameters of the parallel capacitor, perform reactive power compensation, and improve the power factor cos.
