Triple Resonance Transformer Pulse Generator

reference paper [7]

To reduce voltage stress on the pulse transformer,
a triple resonant pulser with an air cored spiral strip pulse transformer is designed and manufactured.
The tested output of the system was about 300 kV voltage output with about 200 ns pulse width in a 100 Ω load.
The system is very compact in size (1.28 m diameter and 1.06 m height).
Total voltage step-up ratio is about 11.
To form square waveform, a distributed PFN was used.
