A sub-microsecond-range pulse generator based on anti-resonance network and transmission line transformer

Area of Science:

• Electrical Engineering
• Pulsed Power Systems

Background:

• Generating sub-microsecond voltage pulses requires specialized equipment.
• Existing pulse generators may face limitations in pulse quality or voltage gain.

Purpose of the Study:

• To present a novel pulse generator design for sub-microsecond pulses.
• To utilize an antiresonance network and transmission line transformer (TLT) for pulse forming and voltage boosting.

Main Methods:

• A three-section antiresonance network (TSAN) was employed as the pulse forming module.
• A three-stage transmission line transformer (TLT) was utilized as the pulse voltage boosting module.
• Experimental validation of the generator's performance.

Main Results:

• The TSAN produced a high-quality, fixed flat-top quasi-square pulse with a 400 ns duration and 7.2 kV amplitude from a 15.0 kV charge voltage.
• The three-stage TLT achieved a voltage step-up ratio of approximately 3.05, resulting in an output voltage amplitude of 22.0 kV.
• The generator demonstrated low loss in transmitting voltage pulses.

Conclusions:

• The combined TSAN and TLT design effectively generates sub-microsecond pulses with desired characteristics.
• The generator offers efficient pulse shaping and significant voltage amplification.
• The developed pulse generator shows promise for applications requiring high-quality, high-voltage, short-duration pulses.
