Problems solved by technology

However, these pulse generators basically use gas spark switches, which are large in size and complex in structure. Due to the constraints of factors such as gas ionization recovery and switch electrode surface ablation, it is difficult to achieve stable and reliable repeated conduction at high repetition rates. and shutdown

Embodiment Construction

[0017] The technical solutions of the present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.

[0018] like figure 1 , figure 2 , image 3 , Figure 4 as shown, figure 1 It is a schematic diagram of the main circuit structure of the high-voltage repetitive frequency pulse source; figure 2 is a schematic diagram of the structure of a double-gate hydrogen thyratron; image 3 It is a schematic diagram of a hydrogen thyratron grid trigger circuit; Figure 4 Design the block diagram for the FPGA output trigger pulse.

[0019] For the high-voltage repetitive frequency pulse source of this embodiment, when determining the circuit parameters, the most important thing to pay attention to is the inductance of the main circuit, because the high-voltage pulse source requires a pulse front of nanosecond level, and the steepness of a single pulse front = 0.7L / R , it can be seen that the steepness of the pulse is ...

Abstract

The invention discloses a high-voltage repetition-frequency impulse source based on a GL1551G type hydrogen thyratron. The high-voltage repetition-frequency impulse source based on the GL1551G type hydrogen thyratron is composed of a direct-current power supply, an energy storage system, an impulse power switch and a load. A capacitance energy storage mode is adopted in the energy storage system, a closing switch is needed by the high-voltage impulse source with the capacitance energy storage, the bigrid hydrogen thyratron is a gas switch belongs to closing switches, and the load needs to be noninductive. Through the mode of using an FPGA for achieving multi-impulse source equal interval delayed output, the effect that the high repetition frequency of the high-voltage impulse is tunable can be ensured; through a designed hydrogen thyratron grid trigger circuit, the hydrogen thyratron can be triggered to be connected reliably while the inductance value in a main circuit is reduced, and fast-rise leading edges available in the high-voltage impulse source and elimination of output impulse oscillation can be ensured.

Description

technical field [0001] The invention relates to a high-voltage repetitive frequency pulse power supply. [0002] Background technique [0003] The high-voltage and high-current repetitive-frequency pulse power supply with nanosecond-level rising front is widely used in production and scientific research fields such as accelerators, nuclear explosion simulations, laser plasma diagnostics, high-resolution radars, and electromagnetic pulse simulators. In a pulse power system, it is impossible to directly obtain the high pulse power required by a certain waveform from the power grid. Generally, the energy is stored for a long time with the help of an energy storage system, and then released instantaneously. Get pulse strong current and high power. [0004] The output pulse of the traditional high-power pulse source is difficult to meet the requirements of high voltage, high repetition rate and fast rising front. A lot of research has been done on the high-voltage and high-curr...
