Abstract :
This paper presents the calculation of a time-harmonic eddy-current field in combination with capacitive circuit devices. The computation has been performed by a weak coupling of the circuit and the field equations. An incomplete solution of the system matrix and a scaling of the matrix by the new resonance frequency have been realized to accelerate the calculation process. The calculation method has been applied to the technically important field of resonance inverters supplying an induction furnace. The results agree well with measurement data
