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 equation in the electromagnetic devices. The equations are established in automatic way: the circuit equations are put in a state form and the field equations are discretized using FEM. An original way of linking the two systems of equations is proposed.
