A Novel Topology of Hybrid HVDC Circuit Breaker for VSC-HVDC Application [PDF]
Energies, 2017 The use of high voltage direct current (HVDC) circuit breakers (CBs) with the capabilities of bidirectional fault interruption, reclosing, and rebreaking can improve the reliable and safe operation of HVDC grids. Although several topologies of CBs have been proposed to perform these capabilities, the limitation of these topologies is either high on ...
