Description
technical field [0001] The invention relates to a novel high-voltage square wave pulse generation system, which belongs to the technical field of pulse power. Background technique [0002] The pulse power system refers to an electrical device that compresses pulse energy and obtains high power and short pulses. The working principle of most pulse power devices is as follows: the initial energy storage (such as Marx generator, capacitor bank, high-energy explosive, etc.) formed by various forms passes through the pulse forming system and the transfer switch, and the high-power, short-pulse energy is quickly released. The usual pulse square wave generating device first uses a Marx generator to form an initial high-voltage pulse of the order of microseconds, then uses a pulse forming line to shape the pulse, and finally obtains a high-voltage pulse of the order of nanoseconds on the diode. This type of device requires primary power supply, first-stage pulse compression, and se...
