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
