With the continuous improvement of the proportion of new energy development and utilization in the world, photovoltaic and energy storage systems continue to develop, and their safety and reliability requirements are getting higher and higher. In addition, China vigorously develops the construction of photovoltaic and wind power generation in “Desert, Gobi, desert” area, and its HVDC transmission system has become a research hotspot. The rail transit and aerospace system also use DC power supply. DC circuit breakers play an important role in the control and protection of the above photovoltaic, energy storage, DC transmission and rail transit systems. The ability of circuit breaker to break DC current directly affects the safety and reliability of the whole system. Therefore, the research and development of the key theory and technology of DC breaking has attracted the attention of a large number of domestic and foreign scholars. At present, DC circuit breakers mainly include mechanical DC circuit breakers, hybrid DC circuit breakers and solid-state DC circuit breakers. This session mainly discusses the DC breaking theory and new technology for the above applications.

Topics of interest for this special session include, but are not limited to:

(1) Theory of DC breaking.
(2) DC vacuum arc characteristics.
(3) DC air arc characteristics.
(4) DC arc simulation.
(5) Advanced technology for HV/LV DC breaking .
(6) Topology and characteristics of hybrid DC circuit breakers.
(7) Characteristics of solid state DC circuit breakers.
