Abstract

The invention discloses a cable energy-storage multiplex high-voltage pulse generation apparatus. The cable energy-storage multiplex high-voltage pulse generation apparatus comprises a helix pulse generator which is connected to a trigger switch by use of a trigger resistor; a charging cable is connected to the charging interface of the trigger switch; the trigger switch is connected with a blocking capacitor by use of an energy-storage cable; a trigger output cable is connected to the trigger output cable jack of the blocking capacitor. According to the cable energy-storage multiplex high-voltage pulse generation apparatus, the trigger switch discharges by use of the helix pulse generator, the potential of the inner core of the coaxial energy-storage cable changes suddenly, and high-voltage pulses are output via the blocking capacitor; the output pulses are high in rising rate which can be 20kV / ns, low in jittering which does not exceed 2ns, and high in anti-interference capacity, and further can be expanded to multiple outputs easily; the amplitude of the output pulses can be a hundred kV, and the rising time is several nanoseconds; compared with the prior art, the cable energy-storage multiplex high-voltage pulse generation apparatus is obvious in improvement.

Description

technical field [0001] The invention relates to the technical field of pulse power, in particular to a multi-channel high-voltage pulse generating device for cable energy storage. Background technique [0002] High-voltage fast pulse generators have important applications in high-power devices, and have been developed rapidly in recent decades. Pulse generators have reached a higher level. When the circuit is open, the output amplitude can reach more than 100kV, and the rise time and delay Jitter can be less than 10ns. As the application requirements become more and more demanding, the demand for high-voltage pulse generators is also increasing. For example, large-scale pulse power devices must have waveform adjustment capabilities, which need to be realized by triggering the discharge of different capacitor banks through different high-voltage pulse generators. Therefore, it is necessary The high-voltage pulse generator has strong anti-interference ability and is not affec...
