Design of LVDC Bidirectional Hybrid Circuit Breaker

2021 IEEE Fourth International Conference on DC Microgrids (ICDCM), 2021
One of the most challenging hindrances to the spread use of the DC grids is their protection devices. Due to the absence of zero crossing, when a fault occurs, arc extinction becomes an issue for the traditional mechanical circuit breakers. Thanks to the recent advances in solid-state circuit breakers, this problem is solved because of the absence of ...
