Optimization Design and Performance Research for Solid-state Bus-tie Switch of Marine DC Grid
Marine DC power grid typically sustains high current when shorted and its electric characteristics are extremely susceptible to influence by the stray parameters. Given the limitations of cabin space, it is necessary for the bus-tie switch of the DC grid

Design of a snubber circuit for low voltage DC solid‐state circuit breakers [PDF]
Abstract Solid‐state circuit breakers (SSCBs) are designed to interrupt fault currents typically several orders faster than its electromechanical counterparts. However, such an ultrafast switching operation would produce a dangerous overvoltage which might cause damages to SSCBs and other circuit elements in the system.

In this text three different solid state circuit breakers (SSCB) for medium voltage direct current (MVDC) systems have been investigated, namely the interrupting, the current limiting and the resistive topologies. In particular, design strategies for each breaker topology has been proposed emphasizing the optimal design of passive elements with regard ...

Solid-State Circuit Breaker Component Simulation
The landscape of direct current (DC) solid-state circuit breakers (SSCBs) is growing and so too is the choice of primary components. There now exists a wide range of devices capable of withstanding voltage levels conducive to electrical transmission; though steady state efficiency of these devices remains a concern.
