Abstract

The present disclosure discloses a megajoule pulse xenon lamp pumped power supply with modular design, which comprises an energy storage part, a current conduction and load part, a busbar, a constantcurrent charger and a bleeder switch. The invention eliminates a damping inductance necessary in the existing technical solution to improve the energy utilization efficiency of the xenon lamp load onthe basis of ensuring the safety performance of the device; meanwhile, multiple sets of capacitors share a charger and a bleeder switch so that an economical, safe and efficient solution is provided for the application of a semiconductor switch and highly flexible current pulse output.

Description

technical field [0001] The present disclosure relates to a high-power pulse xenon lamp power supply, in particular to a modularized megajoule pulse xenon lamp pump power supply. Background technique [0002] The xenon lamp pump power supply is an electrical device that stores electrical energy, drives the discharge of the pulsed xenon lamp, and provides an appropriate current pulse for the pulsed xenon lamp. It is often used in high-power solid-state lasers. Existing large-scale xenon lamp power supplies can store energy up to several megajoules. Generally, multiple capacitors are charged in parallel. After charging is completed, a high-current switch conducts all parallel capacitors to discharge to the load xenon lamp. [0003] However, the circuit configuration and technical scheme of the existing large xenon lamp power supply have obvious defects: [0004] First, in order to ensure the safety when multiple capacitors are connected in parallel, damping inductance, or prot...
