Design considerations of series type hybrid circuit breaker (S‐HCB)

IET Power Electronics
The series‐type direct current (DC) hybrid circuit breaker (S‐HCB) concept was previously reported to offer better performance than solid‐state circuit breakers (SSCB) and hybrid circuit breakers (HCB).

Hybrid institution vacuum circuit breaker action time prediction

Journal of Physics: Conference Series, 2022
Abstract Phase-control technology requires a sufficiently small dispersion of switching operation times, however, even though the switch itself is sufficiently stable, action time dispersion is still a key issue in phase-control technology due to various factors.

Cascaded commutation circuit for a hybrid DC breaker with dynamic control on fault current and DC breaker voltage [PDF]

, 2017
This paper proposed a cascaded commutation circuit based on current commutation approach for low-to-medium voltage DC fault current interruption, without snubber circuits, which slows the fault current di/dt prior to current-zero and the rate of rise of ...

Design and Implementation of LVDC Hybrid Circuit Breaker [PDF]

IEEE Transactions on Power Electronics, 2019
In recent years, dc distribution grids have become increasingly popular because of the interest in the diffusion of distributed renewable energy. In this scenario, dc distribution grids are also favored because of the increased use of batteries and power electronic loads. The main limit to the spread of dc grids is their protection devices, which still

DC fault protection structures at a DC-link node in a radial multi-terminal high-voltage direct current system [PDF]

, 2016
In a multi-terminal HVDC system, DC circuit breakers (DCCBs) are conventionally connected in a star-configuration to enable isolation of a DC fault from the healthy system parts.
