Voltage source converter–based multiterminal dc (MTdc) grids, including high-and medium-
voltage levels, have attracted attention in recent years and developed fast. To protect the …

DC technologies will be essential building blocks for future DC distribution networks. As in
any DC system, these networks will face crucial threats imposed by short-circuit DC faults …

Piezoelectrically actuated fast mechanical switches provide a low-loss conduction path in
hybrid circuit breakers for protecting medium-voltage direct-current systems. As the desired …

Multiport hybrid dc circuit breakers (M-HCBs) have been recognized as suitable devices for
protecting dc grids. Most M-HCB topologies include load current switch (LCS), leads to …

Due to the significant advantages of low cost, integrated multi-port hybrid DC circuit breakers
(M-HCBs) with a reduced number of devices have attracted extensive attention for fault …

We propose a universal design methodology for multiline hybrid high-voltage dc circuit
breakers (MHCBs) based on a generalized circuit topology. MHCB is a dc circuit breaker …

A massive number of DC circuit breaker is usually necessary to be installed to protect HVDC
grids from DC faults, this will lead to high capital costs because large number of expensive …

We propose a generalized circuit of multiline hybrid HVDC circuit breakers (MHCBs) for high-
voltage dc grids. MHCB is a kind of dc circuit breaker topology that shares a semiconductor …
