This paper focuses on a comparison of the cosimulation schemes for coupled problems with application to coupled electromagnetic field and power-electronic simulations. A co-simulation framework between a finite element solver and a circuit solver based on the waveform relaxation scheme results in an iterative process whose convergence depends on the kind of transmission coupling conditions (TCC) on the interface between the sub-problems. The convergence of TCC is illustrated on two test cases:
