Description

technical field [0001] The invention relates to the technical field of pulse power, in particular to a compact high-voltage controllable Marx generator. Background technique [0002] Pulse power technology is a technology to study the power amplification of strong electric pulses. It stores electric field or magnetic field energy for a long time with low power, and then performs fast energy switching, pulse compression, and power amplification with the help of various switches. The pulse electromagnetic energy is released to a specific load within a certain time, that is to say, the pulse energy is compressed in the time dimension to obtain high peak power output in a very short time. [0003] In high-power pulse technology, Marx generators are mostly used as primary energy sources. Marx generators can generate megavolt-level high-voltage pulse signals through parallel charging and series discharging at low charging voltages. The SINUS and RADAN series products developed by...

Problems solved by technology

[0004] However, due to the extremely high pulse voltage generated by the general Marx generator, it is easy to cause the pulse capacitor, especially the capacitor connected to the reference earth, to withstand a very high overvoltage pulse and break down, which reduces the overall reliability of the Marx generator and threatens its safe

Another bottleneck of the Marx generator is that the steepness of the pulse front is not easy to guarantee, and the ignition action of each gap is not easy to synchronize
