In recent years, with the vigorous development of power electronic technology, renewable energy sources such as wind power and solar energy utilization efficiency continuing to improve, and the application scale expanding unceasingly, DC power grid technology and the development of multiterminal HVDC has become a key link of transmission technology in our country. As the key equipment of biulding DC system, The direct current breaker need to be optimized on the aspect of topology, to promote the development of dc transmission. This article puts forward a new type of submodule which can be applicated in hybrid DC breaker. After a brief review of DC circuit breaker research status, the paper will give the topology structure, and analyzes its working principle. Then, verification and electrical stress calculation will be done in Saber Sketch simulation. Based on this, two other present scheme will be introduced, and finally a comparison will be made between the diffent scheme. As is concluded, the novel submodule can save the power elctronic device cost effectively
