Review of Research Status of Hybrid HVDC Circuit Breakers
With great progresses of flexible HVDC transmission technology in the last three decades
lots of researches are focused on the investigation HVDC circuit breaker at home and abroad.The heavy demand for HVDC circuit breaker used in HVDC system is discussed in this paper based on the development trend of HVDC transmission technology.Furthermore
the development history
topology structure and operational principle of widely used hybrid DC circuit breaker are introduced.Based on these characteristics mentioned above
three technique schemes of hybrid DC circuit breaker including IGBT cascaded topology with double-direction switch
H full-bridge converter topology and IGBT full-bridge transfer branch topology with diode devices are compared adequately.At last
the technical difficulties and future development direction of the study nowadays on hybrid DC circuit breaker are summarized.
