Development of high voltage and high power pulse charging power supply with burst repetition frequency

Abstract： In order to meet the charging requirements of the repetitive pulse power source based on inductance isolated Marx generator, a burst repetitive high-voltage and high-power pulse charging power supply was designed and developed. The power supply adopts the pulse transformer technology route, with a designed charging voltage of 90 kV, charging current of 1 kA, adjustable charging repetition frequency of 1~100 Hz, and a maximum burst charging frequency of 5 times. This article introduces the working principle of charging power supply, conducts circuit parameter calculation and structural design, and obtains the parameters of main components such as thyristors, primary power supply, and pulse transformers. This power supply charges a compact Marx generator with an equivalent total capacitance of 0.7 μF, achieving a charging voltage of 90 kV, a charging time of less than 120 μs， and technical specifications for charging repetition frequency of 10 Hz. The development of this power supply has reference significance for further miniaturization research of high-power repetitive pulse power sources.
