Influence of load loop inductance on output waveform of low-impedance pulse forming line

A lowimpedance experimental platform based on strip pulse forming line(PFL) is introduced. Two different types of matching loads for the platform are designed and tested. The results show that the rail water load has very low inductance and is qualified to be the matching load for the low-impedance PFL. Load loop inductance is the decisive factor that affects the output waveform quality of the low-impedance PFL, when the inductance of the switch is constant. When the load loop inductance is less than 30 nH, the output voltage waveform is a quasi-square wave for the impedance of strip PFL being 0.5 Ω. Moreover, the influence of load loop inductance on the output waveform of PFLs with different impedances is analyzed by numerical simulation. The influence is found to decrease with the in
