摘要：

This paper addresses the methods to retain the functionality of the soft-switching current-fed converter in the case of transistor fault. Various primary-side transistor faults and corresponding scenarios to minimize the influence on the converter characteristics are presented. The proposed method allows preserving the power delivery and converter soft-switching operation in the case of fault of one of the primary side transistors. Post-fault operation was experimentally verified using a 500W converter prototype, and resulting implications for converter efficiency were analyzed.
