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.
