The development of large scale DC microgrid and high voltage direct current (HVDC) power grid requires a reliable, fast and low-loss circuit breaker. In spite of the advantages of DC gird such as low ...

The key obstacle in integrating high-voltage direct current (HVDC) point-to-point networks into meshed multiterminal HVDC networks (MTDC) is the absence of dc circuit breakers (DCCBs), which can ...
