N2 - 270V DC power supply system is becoming a new trend of development in aerospace field, while the reliable circuit breaker is a key factor to the application of high voltage DC. The technologies of circuit breaker were researched and a new hybrid breaker applied to aero 270V DC system was designed. Firstly, based on the operation principle, the transient characteristics of hybrid breaker were theoretically analyzed. Then the design principles of capacity in buffer branch and varistors in absorption branch were given. Secondly, the transient characteristics in buffer and absorption processes were intensive studied with designed topology by simulation software. The simulation results show that overvoltage of the source side was limited during interruption with the proposed topology. Then, 100A rated miniaturization hybrid breaker prototype with the breaking capability of 2200A was tested. Finally, the characteristics during interrupting were experimentally obtained. The buffer process and absorption transient process were verified. Meanwhile, it was pointed out that over-current failure was a main factor of influencing the performances of the hybrid breaker.
