摘　　要：随着直流输配电系统在多端高压直流输电系统、船舶电力系统、轨道交通等应用领域的扩展,直流断路器作为关键设备成为研究热点。国内外学者提出了多种直流分断方法和策略,其中电流转移分断是直流断路器开断的一种有效方式,而换流技术是其中的核心内容。根据换流原理和电力电子器件的使用情况,将换流技术主要分为了被动换流、主动换流、集成换流。综述了这3种换流技术相关的研究和工程应用,并对目前存在的关键技术问题以及未来的研究发展进行了探讨与分析。With the rapid development of the multi-terminal high voltage direct current system,the ship power system and the subway power system,DC circuit breaker（ DCCB） has also become a new hot research area in electrical engineering. Researchers put forward various DC interruption topologies. The current-transfer interruption is an effective way in DCCB,and commutation topology is the key content. The key point of DCCB development is commutation circuit selection and design,the commutation characteristics,energy absorption parameters and reliability. According to the principle of the commutation and the power semiconductor,there mainly have been three types of commutation topology,such as active commutation,passive commutation and combination commutation. In this paper,the relative study and engineer application on the three commutation topologies were reviewed,and some points for the future development were presented.
