With the aim of making the system modular and scalable to different powers/energies, series-connected partial power converters are proposed. Serializing these converters entails significant overvoltage issues, and this paper tackles them for one series-connected module failure case. A reliability analysis has been carried out considering that the components of the battery system follow an independent and identical distribution in terms of failure probability. Furthermore, a redundancy factor has been added to allow a certain failure rate in what is known as a fault-tolerant system. Finally, to demonstrate the high efficiency of partial power converters, a 3 kW prototype is tested at different working points that model the charging process of a battery. The experimental results show a peak efficiency of 99.36%. 2079-9292 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=173277 https://hdl.handle.net/20.500.11984/6233 electric vessel energy storage system (ESS) hybrid modular converter DC–DC power converter partial power processing (PPP) partial power converter (PPC) dual active bridge (DAB) High Efficiency Converters Based on Modular Partial Power Processing for Fully Electric Maritime Applications
