摘　　要：本文设计了一种应用于脉冲功率电源的高压、大容量、长寿命金属化膜电容器。从理论计算出发,对照经验数据库,综合考虑电容器的额定电压、峰值电流、工作频率等指标,得出膜材取值范围和电容器可选元件子集;应用计算机3D拟合等仿真技术,反复迭代出匹配基材的最优元件大小及元件空间布局方案,确定了电路拓扑、芯子结构及绝缘方案。同时,搭建全工况试验平台,测试了电容器的电压、工作电流、寿命等性能指标。测试结果表明:电容器容值217μF,在额定电压为35 kV、工作电流为35 kA、反峰大于10%工况下,寿命大于40000次。A high-voltage,large-capacity,and long-life metalized film capacitor used in pulsed power supplies was designed.Starting from theoretical calculations,comparing with the empirical database,comprehensively considering the capacitor's rated voltage,peak current,working frequency and other indicators,the film material value range and the subset of capacitor optional components were obtained;computer 3D fitting and other simulation techniques were used to iterate repeatedly.The optimal component size and component space layout plan of the matching substrate was developed,and the circuit topology,core structure and insulation plan were determined.A test platform for all working conditions was built to test the capacitor's performance indicators such as voltage,working current,and life.The test results show that the capacitor has a capacitance value of 217μF,a rated voltage of 35 kV,an operating current of 35 kA,an inverse peak greater than 10%,and the service life is greater than 40,000 times.
