Developing a solid-state quasi-square pulse Marx generator.

Area of Science:

• Electrical Engineering
• Pulsed Power Systems
• High-Voltage Technology

Background:

• Traditional Marx generators utilize spark gap switches, which can limit performance and reliability.
• The need for more robust and controllable high-voltage pulse generation is critical in various scientific and industrial applications.
• Existing pulse-forming networks often struggle to produce precise quasi-square pulse shapes efficiently.

Purpose of the Study:

• To design, construct, and test a novel all-solid-state quasi-square pulse Marx generator.
• To replace conventional spark gap switches with a fractional-turn ratio saturable pulse transformer (FRSPT).
• To integrate a three-section anti-resonance network for pulse shaping.

Main Methods:

• Development of a Marx generator incorporating thyristors as primary switches.
• Implementation of a fractional-turn ratio saturable pulse transformer (FRSPT) as a pulse modulating switch.
• Utilization of a three-section anti-resonance network as the pulse-forming module.

Main Results:

• Successful construction and testing of the all-solid-state quasi-square pulse Marx generator.
• Achieved an output quasi-square pulse with an amplitude of 18.5 kV and a pulse width of 3.15 μs at a charge voltage of approximately 1000 V.
• Experimental data validated the performance and feasibility of the proposed design.

Conclusions:

• The integration of FRSPT and anti-resonance network enables a viable all-solid-state quasi-square pulse Marx generator.
• This approach offers a promising alternative to traditional Marx generators with spark gap switches.
• The demonstrated performance highlights the potential for advanced pulsed power applications.
