N2 - DC microgrids have attracted more and more attention due to their excellent performance. However, the development of DC microgrids is restricted by DC short-circuit protection technology. In this paper, a novel bidirectional Γ-source solid-state circuit breaker (BΓSCB) based on three-winding coupled inductors is proposed to ensure the safe operation of DC microgrids. Compared with other solid-state circuit breakers, the novel BΓSCB has a simpler structure and more compact size. First of all, the derivation process and operation principle of the novel BΓSCB topology are elaborated. Then, an accurate mathematical model covering the whole fault transient and considering the reverse-recovery requirement of SCR is established, and the active trigger region is also quantified, which provide effective guidelines for BΓSCB design and component sizing. Finally, the effectiveness of the proposed BΓSCB topology and the accuracy of the modeling method are verified by simulations.
