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.
ㆍ Voltage Step-up Ratio: 11
ㆍ Peak Output Voltage: ~ 300 kV max.
ㆍ Pulse Repetition Rate: Single shot
ㆍ Pulse Width: ~210 ns
ㆍ Load Impedance: ~100 Ω
ㆍ Dimension (Height [cm] x Dia. [cm]): 106 x 128
