According to the material and the craft characteristics, high-voltage pulse discharge and store performance of lately developed CT47 type pulse power capacitor based on Zr-Ba-SiO3 is analyzed. Then, a series of performance search experiments is designed according to pulse power application scenes. The result indicates that this capacitor has preferable temperature performance, steady high voltage pulse discharge characteristic, high permissible voltage, and excellent insulation capability. Above-mentioned analysis and experiment lay a good foundation in the application of pulse power realm for the capacitor.
