Abstract: Reluctance-conductance network (RCN) for 3D eddy current calculation is presented. The proposed RCN has been formed by means of the FE method using the A-V formulation. The finite element is assumed to be an edge element in relation to magnetic potential A and a nodal element in relation to electric potential V. The edge values of A represent the loop fluxes in the reluctance network. The time derivatives of loop fluxes create electromotive forces in the branches of the conductance network. The RCN formed by the BE method has mutual reluctances and mutual conductances. To calculate the integrals that describe the conductances an approximate formula is proposed. This formula gives the model of rectangular prism without mutual conductances. An example of the application of the RCN method is presented. The results for the RCN with mutual conductances and the RCN without these conductances are compared.
