English Abstract

Current-fed isolated bidirectional dc–dc converters (CFIBDCs) are suitable solutions for feeding batteries. However, maintaining high efficiency over wide input and output voltage (IOV) range remains a challenge for them. This article proposes a hybrid CFIBDC intended for wide IOV range operation, which is constructed by integrating a current-fed dual-active-bridge and an LC-resonant converter (LC...
