Double-cell experimental study of linear transformer drivers

The technical path combining pulse forming with inductive adding is one of the important candidates to realize pulsed power miniaturization. In this paper, the cell structure of the linear transformer driver(LTD), which is based on pulse forming network(PFN), with impedance 2.5 and pulse width 200ns is introduced. The outputs of two such LTDs are inductively added to a load through the cathode pole, which forms a double-cell module based on the LTDS. The experiment results show that the high-voltage pulse waveform from the double-cell module at charging voltage of 40 kV and repetition frequency of 20 Hz/40 Hz accords with that from PFN discharged directly, and its jitter is about 2 ns. The coherence of the output pulse waveforms is quite good at repetition mode.
