Design criteria of solid‐state circuit breaker for low‐voltage microgrids

Solid-state circuit breakers (SSCB) show great promise to become the key element in protection of low-voltage direct current microgrids. SSCBs operate microsecond range and employ semi-conductor devices that have strict safe operation area limits. Therefore, design SSCB needs consider effects fault detection delays limitations. This paper derives criteria effect different methods with under varying system constraints. The space is investigated a sensitivity analysis, which provides insights into boundaries explains how combination can reduce size. from theoretical analysis are used propose an flowchart. prototype developed tested scenarios nominal grid voltage current. derived constraints be for efficient also evaluate schemes on required
