Influence of leakage resistance on charging efficiency of water dielectric pulse forming line

A pulsed power system is now under development. The water dielectric pulse forming line(PFL) was adopted as the wave forming part and charged by a storage capacitor via pulse transformer. The influence of leakage resistance on charging efficiency of the water dielectric PFL was analyzed. Leakage resistance of the PFL was calculated to be between 8.2 kΩ and 3 kΩ. Energy efficiency and voltage efficiency during the charging process were estimated for different module numbers, and the result shows that the energy loss rate is about 5%～12% and increases when the module number grows.
