The ring pulse forming line which uses BaTiO3 material is developed. Material characteristics and the influence of electric field distribution on the electric strength of the pulse forming line are analyzed. Due to optimizations of structure design and material characteristics, the electric strength of the pulse forming line has been enhanced. A 37-stage compact Marx generator is designed based on the pulse forming line. The electric field intensity distributions of the configuration with inductances were simulated. According to the results of the simulation, the electric field of the configuration is uniform and gives an optimized contour dimension. In the experiment, when the PFL was charged at ±19 kV, the output voltage was more than 680 kV and the pulse width was about 65 ns on the matching load.
