Diode-Bridge Multiport Hybrid DC Circuit Breaker for Multiterminal DC Grids

IEEE Transactions on Industrial Electronics, 2021
Hybrid dc circuit breaker (HCB) is currently the most promising dc circuit breaker. However, since it requires hundreds of semiconductor switches to withstand high transient interruption voltage, the implementation cost is high. Besides, in the multiterminal dc grid, three or more HCBs may be required at a dc bus, which worsens the disadvantages of ...
