The magnetic circuit model of the magnetic saturation characteristic magnetoresistance of the magnetically controlled shunt reactor (MCSR) nonlinear core is proposed by using the magnetic field division method, combining with the geometric parameters and working principle of the prototype. The magnetic circuit structure and working characteristics are analyzed. The calculation formula of the magnetic potential node of the magnetically controlled shunt reactor is derived by improving the node analysis method, and the simulation calculation and analysis of the working current of the magnetic control reactor under no-load and different DC bias are carried out. The conclusion shows that the accuracy of the magnetic circuit model can meet the needs of engineering, and the modeling method has the characteristics of clear principle, simple modeling, accurate model and engineering applicability, which can provide guidance for designers.
