Description

technical field [0001] The invention belongs to the technical field of high-voltage triggering of a pulse power system, and in particular relates to a Marx generator triggered by a photoconductive switch and a trigger circuit based on the photoconductive switch. Background technique [0002] In the pulse power system, the establishment of the primary energy storage Marx generator usually adopts the high-voltage pulse electrical triggering method. Generally speaking, the amplitude of the pulse voltage output by the high-voltage trigger is in the range of tens of kilovolts to hundreds of kilovolts. In order to meet the high-voltage pulse output, the high-voltage trigger mainly adopts the technical route form of Mini-Marx series voltage doubling, boosting based on pulse transformer and multi-stage pulse step-by-step amplification. [0003] The high-voltage trigger based on Mini-Marx follows the circuit of parallel charging and series discharging of Marx. The number of series s...
