A comprehensive review of DC fault protection methods in HVDC transmission systems
High voltage direct current (HVDC) transmission is an economical option for transmitting a large amount of power over long distances. Initially, HVDC was developed using thyristor-based current source converters (CSC).

Overcurrent Protection Control Design for DC-DC Buck Converter With Disturbances [PDF]
This paper deals with the output voltage regulation problem for dc-dc buck converters. Overcurrent protection and disturbances are both taken into consideration. The main challenge of control design is how to ensure that the current constraints are not violated at any time in the presence of disturbances.

A Series-Type Hybrid Circuit Breaker Concept for Ultrafast DC Fault Protection
A new series-type hybrid circuit breaker (S-HCB) concept for dc fault protection is reported that is fundamentally different from other prior-art hybrid circuit breakers (HCB) or solid-state circuit breakers (SSCB) in the literature.
