Description

technical field [0001] The invention belongs to the technical field of wireless energy transmission and high-voltage pulse power source, and in particular relates to a high-power repetition frequency high-voltage pulse power source. technical background [0002] Pulse power technology and high-power pulse power supply were first produced in the 1930s and have developed rapidly since the 1960s, gradually forming an emerging technical field of an independent discipline. Pulse power technology, also known as high-power pulse technology, is an electrophysics research that stores energy for a long period of time, then compresses and converts it quickly, and finally releases it to the load with a very high power density in a very short time. Technology is essentially the amplification of output power to input power. [0003] In order to improve the utilization efficiency of the pulse power source, repetition frequency technology is adopted. The existing solid-state pulse power t...
