A voltage-division-type low-jitter self-triggered repetition-rate switch.

Area of Science:

• Electrical Engineering
• Pulsed Power Systems
• High Voltage Engineering

Background:

• Traditional high-voltage switches often require complex auxiliary systems, increasing size and reducing efficiency.
• Achieving low jitter and high energy efficiency simultaneously in self-triggered switches remains a challenge.

Purpose of the Study:

• To introduce a novel voltage-division (V/N) low-jitter self-triggered multi-stage switch.
• To analyze the operational principles and performance characteristics of this new switch design.

Main Methods:

• The switch design integrates a triggered corona gap, quasi-uniform-field gaps, and an inversion inductor.
• Theoretical analysis was performed to deduce the self-triggered voltage dependence on over-voltage factor and operating voltage.
• Experimental fabrication and testing were conducted to validate performance.

Main Results:

• The V/N switch operates at 1 MV and 50 Hz, producing 1000 successive pulses.
• Achieved a low jitter of 3% and high energy efficiency of 90%.
• Demonstrated potential for high repetition rate operation and long lifetime.

Conclusions:

• The proposed V/N switch offers a compact, efficient, and reliable solution for high-voltage pulse generation.
• The self-triggered multi-stage design successfully overcomes limitations of conventional switches.
• This technology is suitable for applications requiring high repetition rates and long operational life.
