DC microgrids have attracted significant attention over the last decade in both academia and
industry. DC microgrids have demonstrated superiority over AC microgrids with respect to …

High voltage direct current (HVDC) systems are now well integrated into AC systems in
many jurisdictions. The integration of renewable energy sources (RESs) is a major focus …

The proliferation of renewable energy resources to the next level optimizes microgrid
utilization to manage the disturbances effectively. A direct current microgrid achieves …

The development of flexible AC transmission and multi-terminal DC grid is in an urgent
demand for DC circuit breaker (DCCB) technology with faster switching speed, strong …

Characterized by ultra-fast and arc-free fault clearing, solid state circuit breakers (SSCBs)
are getting increasing popularity with the latest development of advanced power …

This paper proposes a new n-port hybrid dc circuit breaker for offshore multiterminal HVDC
grid application. The n-port dc circuit breaker can substitute n-1 hybrid dc circuit breakers at …

This paper proposes a coupled inductor-based hybrid dc circuit breaker topology with zero
current switching for fast fault interruption in dc systems. A series resonant circuit comprising …

A Z-source series circuit breaker topology, which allows bidirectional power flow and has the
ability to autonomously disconnect dc faults, is introduced. This topology allows current flow …

In this article, a novel Γ-source circuit breaker (CB) that can offer automatic fault isolation
with no reflected fault current in the feeding source is proposed for the protection of dc …

Multilevel inverters are used in a number of high-power applications, including industrial
motor drives, flexible power transmission, and, renewable energy systems. Since the MLI …
