Transformative Role of Solid-State Circuit Breakers in Advancing DC Systems for a Sustainable World

DC power systems support a more sustainable future by lowering carbon footprints. However, these systems provide significant hurdles in terms of fault protection. DC grids demand faster protection devices because fault currents increase so quickly in microseconds. DC circuit breakers (DCCBs) have established themselves as a popular option for replacing fuses and mechanical circuit breakers. Solidstate circuit breakers (SSCBs) are among the DCCBs that offer ultra-fast protection, noise-free, and arc-free operation with a longer lifespan. This article discusses significant research trends in SSCBs for LVDC and MVDC grid applications, their limitations, and prominent global SSCB producers, including commercial products.
