Abstract: High performance power supply system is the basis for the development of satellite borne, airborne, shipborne and on-board electronic equipment. The pulse power electronic load improves the technical and tactical performance of equipment effectively, however, it also brings new challenges to the independent power supply system of various equipment. The large and frequent fluctuation of load power not only affects the power supply quality of the power system, but also threatens the security, stability and reliability of the power system. The key technologies of independent power supply system facing high peak to average ratio pulse power load from the aspects of the interaction and influence between pulse power load and power supply system, pulse energy management technology, pulse power suppression technology, modeling and stability analysis technology of pulse power independent corona system are comprehensively summarized. The technical challenges faced by the pulse power supply system are further summarized, and the further development direction of high-performance pulse power supply system is prospected.
