An original and natural method of coupling electromagnetic field equations with circuit equations put in a state form

In this paper a general method of coupling static converters with electromagnetic devices is presented. This method is based on the simultaneous solution of the converter equations and the field equations in the electromagnetic devices. The equations are established in an automatic way: the circuit equations are put in a state form and the field equations are discretized using a 2D finite element method. An original way of linking the two systems of equations is proposed.
