摘要：

The conventional part failure analysis only takes into account the type, number, and connection status of the components, so failure rates according to the operating characteristics of the converter cannot be reflected. On the other hand, FTA uses a fault- tree showing cause, effect, and result of the fault, so it can predict the failure-rate considering the operational risk of converter. In this paper, the fault-tree is designed considering the operational characteristics of each of the boost converter and the interleaved boost converter, and the lifetime of both converters are predicted by using MIL-HDBK-217F. The validity of the proposed method is verified by comparing with the part failure analysis. Finally, we compare the weight and volume with MTBF according to the power capacity, and propose the selection guide of the boost converter or IBC in the viewpoint of failure-rate.
