Influence of pulse forming network configuration on efficiency of voltage

A Blumlein pulse forming network (PFN) with 20 impedance was designed by using lumped parameter capacitance and inductance. The three-dimensional models of the pulse forming network in two different connecting configurations were established and simulated via finite integration software. The results show that, 98% voltage transfer efficiency of the PFN in linear connecting configuration can be achieved, and the voltage transfer efficiency of the PFN in folded connecting configuration is close to 90%. The high voltage experiments of the PFN in two different connecting configurations were done, and the experiment results were generally consistent with the theoretical simulation results. In the end, the reason for the difference of the voltage and power transfer efficiency was preliminarily analyzed by calculating the coupling parameter of the PFN in two different connecting configurations.
