N2 - DC Solid-State circuit breakers (SSCBs) play an important role in cutting off the fault current in the DC distribution network. Particularly, SSCBs using single-gate controlled series-connected power devices (SCSPDs) method presents great potential in dealing with the increasing blocking voltage applications. Revealed topologies using the SCSPDs method are investigated at the beginning of this paper, and a novel single-gate driver is proposed by inspiration. The proposed gate driver presents good compactness, improved stability, and increased scalability compared with the conventional drive method. The working principle, including component function and switching transition, are analyzed to master the operation mechanism. Particularly, the gate oscillation problem is observed and is suppressed by the designed structure. Main simulation and experimental tests under various scenarios have been conducted for reference of component selection and verification of the proposed design's effectiveness.
