15-GW repetitive pulsed power generator based on Midel 7131 and double-width pulse forming line

Area of Science:

• Pulsed Power Systems
• High-Energy-Density Physics

Background:

• Traditional Tesla-type pulsed power generators face limitations in size and weight, hindering mobile applications.
• Transformer oil-based systems are bulky and less suitable for portable high-power requirements.

Purpose of the Study:

• To design a compact, high-repetitive pulsed power generator for mobile platforms.
• To overcome the size and weight constraints of existing pulsed power technologies.

Main Methods:

• Development of a double-width pulse forming line (PFL) utilizing Midel 7131 liquid medium.
• Optimization of PFL structural and electrical parameters for a 60 Ω load.
• Integration into a generator with a final size of 4 × 1.5 × 1.5 m³ and weight of 4.7 tons.

Main Results:

• Achieved a peak power of 15 GW with a 50-ns pulse width.
• Demonstrated reliable operation at a 50-Hz repetition rate with <1% voltage jitter.
• Successfully drove an X-band backward wave oscillator, producing favorable microwave output.

Conclusions:

• The developed double-width PFL generator is compact and suitable for mobile applications.
• The generator exhibits high-power driving capability, validated by microwave generation.
• This technology advances the feasibility of portable, high-performance pulsed power systems.
