N2 - Currently, dual-active-bridge (DAB) converters are widely adopted as the power interface to achieve a bidirectional power flow and galvanic isolation in high-frequency dc power transmission systems. However, the power devices are statistically reported as the main factor of possible failures in practical operation, which is harmful to the stability of power electronic dominated systems. Thus, the fault-tolerant capability is essential for the DAB converter to maintain a reliable system operation, which guarantees the avoidance of faults-induced instability. However, the impact of fault fault-tolerant capability on the system reliability is not thoroughly investigated and quantified. In this paper, the DAB converter-based system is modeled by a simplified reliability model and further developed to the Markov process. The reliability of the DAB converter with and without fault-tolerant capability is analyzed with the proposed mathematical model. Meanwhile, the long-term steady-state availability of the system is investigated in this paper.
