DC GRIDS: New over current protection
2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe), 2016Fuses and Circuit Breakers play an important safety role in electrical transportation systems. Challenging new applications, especially in DC grids, have brought conventional current limiting devices to their limits. Indeed, mechanical circuit breakers may be too slow to open for networks with large DC fault currents.
