Electric propulsion and integrated hybrid power systems can improve the energy efficiency
and fuel consumption of different kinds of vessels. 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. [-]
