一种采用LC谐振电路增强功能的新型多端口混合直流断路器

Multiport hybrid dc circuit breakers (M-HCBs) are considered a suitable solution for protecting multiterminal direct current grids, as the expensive main breaker (MB) is shared among adjacent lines connected to a common bus. However, MBs in most M-HCBs still utilize expensive fully controlled semiconductor devices. In this article, a novel thyristor-based multiport HCB (T-MHCB) is proposed to solv...
