초록

Using the inverse current injection method, zero current switching can effectively suppress the surge voltage during SSCB's switch turn-off. However, it requires additional auxiliary components such as resonant circuits and thyristors, which increase circuit complexity and may increase the failure rate. In this paper, Fault Tree Analysis (FTA) is conducted to identify the failure modes of the snubber circuit and to analyze its reliability by reflecting its operational characteristics. It was confirmed that the SSCB's switch exhibits a long lifespan because it does not perform frequent operations, unlike general power electronic systems.
