If the vessel power system is based on DC grid distribution, some benefits such as higher generator e ciency and lower volume and cost can be achieved. However, some challenges remain in terms of protection devices for this kind of DC grid-based power system. The absence of natural zero crossing in the DC current together with the fast and programmable breaking times required make it challenging. There are several papers related to DC breaker topologies and their role in DC grids; however, it is not easy to find comprehensive information about the design process of the DC breaker itself. In this paper, the basis for the design of a DC solid-state circuit breaker (SSCB) for low voltage vessel DC grids is presented. The proposed SSCB full-scale prototype detects and opens the fault in less than 3 us. This paper includes theoretical analyses, design guidelines, modeling and simulation, and experimental results. 2079-9292 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=152832 https://hdl.handle.net/20.500.11984/1669 Breakers Circuit breaker Fault current limiter Direct current DC power grids solid-state DC circuit breaker Design of a Solid-State Circuit Breaker for a DC Grid-Based Vessel Power System
