Numerical simulation of a nonconventional alternator connected to a rectifier

A numerical simulation of a nonconventional alternator connected to a rectifier is proposed. To take into account the interference between the magnetic and electric circuits, the magnetic equations solved with the help of the finite-element method are coupled with the electric equations. The Newton-Raphson algorithm is used to consider the different nonlinearities (magnetic materials and semiconductors). The complete differential equations system is solved with an iterative procedure. With the proposed model, the alternator is modeled for different operating points. The numerical results are compared to the experimental ones, showing the reliability of the proposed numerical model.<
