Controlled Transition Full-Bridge Hybrid Multilevel Converter With Chain-Links of Full-Bridge Cells [PDF]
IEEE Transactions on Power Electronics, 2017 This paper proposes a controlled transition full-bridge (CTFB) hybrid multilevel converter (HMC) for medium and high voltage applications. It employs a full-bridge cell chain-link (FB-CL) between the two legs in each phase to generate multilevel bipolar output voltage.

A fast response full bridge power factor corrector [PDF]
PESC 98 Record. 29th Annual IEEE Power Electronics Specialists Conference (Cat. No.98CH36196), 2002 A fast response full-bridge power factor corrector (FBPFC) is presented in this paper. The power converter is combined by two interleaved boost cells and a conventional full bridge power converter. As the interleaving technique is applied, the input ripple current of the FBPFC is reduced. Experimental result shows that the maximum power factor is 0.98,

A novel ZVS full-bridge converter [PDF]
2016 IEEE 16th International Conference on Environment and Electrical Engineering (EEEIC), 2016 Conventional soft switching techniques are promising for improvement of efficiency in full bridge converters. However, efficiency of converters with employing such techniques is restricted due to narrow range of zero voltage switching (ZVS). In such situation, several methods have been proposed in the literature to cope with wide range of ZVS from no ...
