Abstract

2-D saturated electromagnetic systems associated with nonlinear electric circuits are analyzed. The nonlinear electromagnetic equations are modeled with the help of finite elements. The nonlinear electric equations are directly coupled with the electromagnetic ones, and the Newton-Raphson method is used to solve the resulting matrix system. Numerical results for a saturated magnetic core coil fed by an electric source through a diode are reported. The results illustrate the importance of coupling the two systems of equations
