Problems solved by technology
[0004] However, the disadvantage of the above-mentioned technical solution is that the energy storage density is low, and it is only suitable for building a pulse power supply basic module with an energy level of tens to hundreds of kilojoules, and is not suitable for directly building a pulse power supply with an energy level of tens to hundreds of megajoules. Overall system: As far as the construction of the overall system is concerned, an easy-to-implement solution is: first build dozens to hundreds of basic modules based on the pulse power supply, and then connect all the basic modules in parallel to build the overall system
