The development of large scale direct current (DC) transmission system with high efficiency and stability of DC grids has been studied widely. The dc circuit breaker (DCCB) is introduced to ensure the stability of DC grids. Among different types of DCCB, hybrid DCCB has gained more attention. This paper proposes a novel hybrid DCCB topology based on inverse current injecting method. The proposed DCCB topology is able to perform the operation duty of reclosing and rebreaking. In addition, this paper also considers the bidirectional topology of dc circuit breaker with bidirectional current breaking capability. The operating characteristics of the proposed DCCB topology are verified by simulations in Matlab/Simulink environment.
