摘　　要：　电容器是脉冲功率设备的重要储能元件,提高电容器的储能密度能有效地减小脉冲电源的体积。根据箔式结构电容器的缺点及其击穿机理,采用金属化膜和混合膜结构技术,研制出了两种高储能密度高压脉冲电容器,储能密度分别超过800J/L和500J/L。Capacitors are important storage components in pulsed power equipment. In order to reduce the volume of the power source equipment, the energy storage density of the capacitors must be increased. This paper describes the basic breakdown mechanism of capacitors. To avoid the disadvantage of filmfoil type capacitors, the authors present two new techniques, which are metallized film structure and mixedfilm structure. The energy density of two kinds of capacitors is over 500J/L.
