Efficient integration of buck converter into an active rectifier for DC-fault current limitation in DC networks

open access: yese-Prime: Advances in Electrical Engineering, Electronics and Energy
Voltage Source Converters (VSCs) operating as active rectifiers inherently lack current-limiting capabilities for faults occurring on the DC side due to the presence of freewheeling diodes in IGBT or MOSFET structures.

Feasibility and Simulation Study of DC Hybrid Circuit Breakers

open access: yes, 2014
Interruption of DC is more challenging than that of AC because of the absence of DC zero-crossings. This thesis proposes an alternative counter-voltage (ACV) DC hybrid circuit breaker (DC-HCB).

A DC circuit breaker for an electric vehicle battery pack

open access: yes, 1999
Electric vehicle battery packs require DC circuit breakers for safety. These must break thousands of Amps DC at hundreds of Volts. The Sunshark solar racing car has a 140V 17Ahr battery box which needs such a breaker.

Partial Reconfiguration of Multi-Terminal Bipolar HVDC Systems for Continuous Operation of Offshore Wind Power Plants

open access: yesIEEE Access
High-voltage dc (HVDC) transmission systems are commonly used to connect offshore wind power plants (WPPs) with onshore ac grids. However, conventional half-bridge-based modular multilevel converters (MMCs) are vulnerable to dc faults, making it ...
