Area of Science:

• Electrical Engineering
• Pulsed Power Systems
• High Voltage Technology

Background:

• Developing efficient and reliable high voltage pulse power supplies is crucial for various scientific and industrial applications.
• Achieving precise synchronization of multiple output voltages in pulsed power systems presents a significant engineering challenge.
• Existing designs often face limitations in terms of stability, efficiency, and synchronization accuracy.

Purpose of the Study:

• To design and construct a novel solid-state high voltage pulse power supply capable of delivering three synchronous output voltages.
• To investigate the performance characteristics of a fractional-turn ratio saturable pulse transformer (FRSPT) when used as both a step-up transformer and magnetic switch.
• To evaluate the synchronization accuracy and stability of the developed pulse power supply under varying operating frequencies.

Main Methods:

• The pulse power supply was designed incorporating a fractional-turn ratio saturable pulse transformer (FRSPT) and three six-stage Marx generators.
• The FRSPT was engineered to function as both a step-up pulse transformer and a magnetic switch for the Marx generators.
• Magnetic switches were developed using two communal cores to ensure precise multiple-pulse synchronization.

Main Results:

• The experimental setup successfully generated three synchronous output voltages, each reaching an amplitude of approximately 168 kV.
• The voltage rising time was measured to be around 102.6 ns when utilizing a 2 MΩ dummy load.
• The system demonstrated stable operation across frequencies of 1, 5, 10, and 15 Hz, with synchronization jitters consistently below 1.5 ns.

Conclusions:

• The developed solid-state high voltage pulse power supply effectively achieves precise synchronization of multiple output voltages.
• The integrated FRSPT design serves as an efficient component for both voltage step-up and magnetic switching.
• The system's stable performance and low synchronization jitter make it a promising solution for demanding pulsed power applications.
