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.
