Problems solved by technology

[0006] The solid-state Marx pulse voltage superimposer is limited by the maximum current capacity of a single solid-state switch, and it has always been unable to greatly increase its output current

However, simply using solid-state Marx pulse voltage superimposers in parallel will easily lead to unbalanced output current of each pulse voltage superimposer, and local switching tubes are prone to overcurrent damage, which will cause fires, explosions and other problems, posing a great safety hazard

[0007] The solid-state LTD pulse current source is limited by the saturation problem of the magnetic core, and cannot output pulse waveforms with long pulse widths

In addition, since the solid-state LTD pulse current source uses a magnetic core directly at the power end of the power supply for energy coupling, the loss of the magnetic core is very serious, and the energy efficiency is generally low. At the same time, an external reset circuit is required to avoid saturation of the magnetic core.
