In this paper

a kind of self-healing DC-link capacitor for the flexible HVDC transmission project is introduced. The detailed description is made mainly from such aspects as design and manufacture of the product

including selection of metallized polypropylene film material

design of components and core and design of the product structure etc. The key problem existed in the research and development as well as production period of the capacitor and solution process are mainly described

the type test result of the prototype is analyzed and each parameter of the prototype meets related international requ-irement. This paper can provide reference for the design and manufacture of the self-healing DC-link capacitor.
