Hybrid DC Circuit Breaker Feasibility Study
IEEE Transactions on Components, Packaging and Manufacturing Technology, 2017Recently, a growing number of dc systems exist based on the development of electrical energy consumption. For low-voltage dc grids, switching devices are needed that have to meet technically sophisticated requirements. These devices have to handle fault currents of several hundred amperes and system voltages up to 1000 V.

A Survey on Mechanical Switches for Hybrid Circuit Breakers
2019 IEEE Power & Energy Society General Meeting (PESGM), 2019Hybrid circuit breakers are a class of protection devices to facilitate fault current limitation and fast interruption in AC and DC power systems. They are one of the key enabling technologies of multi-terminal DC transmission and distribution systems. As the power rating of DC power systems increases, mechanical switches in the normal conduction path ...
