High-power pulse generator and high-power pulse power supply

Abstract

The invention belongs to the technical field of high-power pulses, and particularly discloses a high-power pulse generator, a high-power pulse power supply and a high-power pulse generation method. The pulse generator comprises a main body composed of multiple stages of pulse modules connected stage by stage; and each pulse module generate an output waveform in response to a driving signal. Each pulse module comprises an energy storage capacitor with a first end and a second end, a plurality of equipotential solid-state switches, first isolation devices and second isolation devices, wherein each solid-state switch comprises a driving end, a first power end and a second power end, and the second power end is connected with the second end of the energy storage capacitor; the first isolationdevices are connected between the first end of the energy storage capacitor and the first power ends of the solid-state switches in series; and the second isolation devices are connected between the second end of the energy storage capacitor of the pulse module and the second power ends of the solid-state switches of the adjacent stage of the pulse module in series. The pulse generator has the beneficial effects that a high-power pulse output with a high voltage, a high current, a fast edge and a wide pulse can be generated.

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 hazar
