Description

Technical Field

[0001] This invention belongs to the field of power electronic device application technology, specifically relating to a primary and secondary fusion system-level interference generator device based on self-breakdown discharge. Background Technology

[0002] Most existing high-frequency damped oscillation wave generators use a method of charging and storing energy in an energy storage capacitor, and then controlling the opening and closing of a high-frequency electronic switch group to release energy onto a resonant LC load, thereby outputting the desired damped oscillation wave. Due to the technical limitations of electronic switches, it is difficult to generate damped oscillation waves with amplitudes above 10kV using the traditional series-parallel electronic switch scheme. Since the charging and discharging of the capacitor takes time, it is difficult to generate damped oscillation interference waves with repetition frequencies exceeding 1MHz. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a primary and secondary fusion system-level interference generator device based on self-breakdown discharge, which addresses the shortcomings of the prior art and solves the technical problem of low output voltage amplitude and repetition frequency of attenuated oscillation wave generator.

[0004] The present invention adopts the following technical solution:

[0005] A primary and secondary fusion system-level interference generator device based on self-breakdown discharge includes a power frequency AC power supply. The M terminal of the power frequency AC power supply is connected to the G terminal of an adjustable gap and the C terminal of a series resonant load group via a current-limiting inductor. The H terminal of the adjustable gap is connected to the N terminal of the power frequency AC power supply and the D terminal of the series resonant load group. The N terminal of the power frequency AC power supply, the H terminal of the adjustable gap, and the D terminal of the series resonant load group are connected to a ground wire. The C and D terminals of the series resonant load group serve as the output terminals of the primary interference waveform.

[0006] Specifically, the series resonant load group includes several series RLC resonant branches, which are connected in parallel.

[0007] Furthermore, the series RLC resonant branch is equipped with an isolating switch.

[0008] Furthermore, the series RLC resonant branch includes at least three branches.

[0009] Furthermore, the series RLC resonant branch includes a capacitor, one end of which is connected to the C terminal of the series resonant load group via a switch, and the other end of which is connected to the D terminal of the series resonant load group via a resistor and an inductor in sequence.

[0010] Furthermore, the two ends of the inductor are the output terminals of the damped oscillating wave, and terminal B is grounded.

[0011] Specifically, the adjustable gap is a telescopic structure.

[0012] Furthermore, the H end of the adjustable gap is fixed, while the G end is driven by a motor.

[0013] Specifically, the interference generator can generate bipolar repetition rate attenuated oscillating waves with an amplitude of 10kV or greater.

[0014] Furthermore, the average waveform amplitude of the repetition-frequency decaying oscillation wave is 10–20 kV, and the repetition frequency is 1 MHz–300 kHz.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] This invention discloses a primary and secondary fusion system-level interference generator device based on self-breakdown discharge. By increasing the power frequency AC power supply voltage, the gap is broken down multiple times to achieve discharge of the resonant circuit and generate a damped oscillation wave. This avoids the problems of voltage equalization, current equalization and synchronous triggering caused by using multiple electronic switches in series and parallel. The device has a simple structure. Since the breakdown voltage of the telescopic adjustable gap is very high, it can easily generate a damped oscillation wave with a high amplitude.

[0017] Furthermore, the series resonant load group includes several series RLC resonant branches, which are connected in parallel to achieve adjustment of the output frequency of the damped oscillation wave.

[0018] Furthermore, each series RLC resonant branch is equipped with an isolating switch to enable switching between different resonant branches.

[0019] Furthermore, the number of series RLC resonant branches can be changed as needed to make the device more streamlined.

[0020] Furthermore, inductors and capacitors in each branch are used to adjust the frequency of the output damped oscillation wave, while damping resistors are used to adjust the decay rate of the damped oscillation wave.

[0021] Furthermore, the two ends of the inductor are the output terminals of the damped oscillation wave, and terminal B is grounded to output a damped oscillation wave based on the ground potential.

[0022] Furthermore, the H end of the adjustable gap is fixed, while the G end can be moved in parallel by a motor, which can adjust the gap distance and thus adjust the breakdown voltage of the gap.

[0023] Furthermore, it can output an amplitude greater than 10kV, which is a significant improvement over existing attenuated oscillating wave generators.

[0024] Furthermore, the repetition frequency of the damped oscillation wave exceeds 1MHz, which is a significant improvement over the repetition frequency of existing damped oscillation wave generators.

[0025] In summary, this invention avoids the technical difficulties associated with series and parallel connection of electronic switches and can output a damped oscillation wave with a high repetition frequency of over 10kV.

[0041] This invention provides a primary and secondary fusion system-level interference generator device based on self-breakdown discharge, which uses a telescopic adjustable gap arc ignition and arc extinguishing as the switch of the resonant circuit, and can generate bipolar repetition frequency decaying oscillation waves with an amplitude of more than 10kV.

[0042] Please see Figure 1 The present invention discloses a primary and secondary fusion system-level interference generator device based on self-breakdown discharge, comprising a power frequency AC power supply 1, a current limiting inductor 2, an adjustable gap 3, and a series resonant load group 4.

[0043] The M terminal of the power frequency AC power supply 1 is connected to the G terminal of the adjustable gap 3 via the current limiting inductor 2; the H terminal of the adjustable gap 3 is connected to the N terminal of the power frequency AC power supply 1; the C terminal of the series resonant load group 4 is connected to the G terminal of the adjustable gap 3; the D terminal of the series resonant load group 4 is connected to the N terminal of the power frequency AC power supply 1; the N terminal of the power frequency AC power supply 1, the H terminal of the adjustable gap 3, and the D terminal of the series resonant load group 4 are respectively connected to the grounding wire 5; the C and D terminals of the series resonant load group 4 serve as the primary interference waveform output terminals.

[0044] Among them, the adjustable gap 3 is a telescopic adjustable gap.

[0045] The power frequency AC power supply 1 can provide a power frequency voltage exceeding the breakdown voltage of the adjustable gap 3, causing the adjustable gap 3 to break down.

[0046] Please see Figure 2 The current-limiting inductor 2 can limit the power frequency AC current when the adjustable gap 3 breaks down. By superimposing a damped oscillating wave to generate a zero-crossing point of the gap current, arc extinguishing is achieved. At the same time, the current-limiting inductor 2 can generate an overvoltage across the gap 3, thereby causing the gap to break down repeatedly and generating a repetitive frequency damped oscillating wave, such as... Figure 3 As shown.

[0047] The adjustable gap 3 serves as a switch for the resonant circuit. The H terminal is fixed, while the G terminal is driven by a motor to move in parallel, thereby adjusting the gap distance and thus the breakdown voltage of the gap.

[0048] The series resonant load group 4 has multiple series RLC resonant branches, and each branch has an independent isolating switch to enable switching of different resonant branches.

[0049] The series RLC resonant branch includes three circuits, each consisting of capacitors C1, C2, and C3 connected in parallel. One end of capacitor C1 is connected to terminal C via switch S1, and the other end of capacitor C1 is connected to terminal D via resistor R1 and inductor L1. The two ends of inductor L1 are connected to terminals A1 and B1, respectively. One end of capacitor C2 is connected to terminal C via switch S2, and the other end of capacitor C2 is connected to terminal D via resistor R2 and inductor L2, respectively. The two ends of inductor L2 are connected to terminals A2 and B2, respectively. One end of capacitor C3 is connected to terminal C via switch S3, and the other end of capacitor C3 is connected to terminal D via resistor R3 and inductor L3, respectively. The two ends of inductor L3 are connected to terminals A3 and B3, respectively.

[0050] In the series resonant load group 4, the inductors AB at both ends of each series RLC resonant branch serve as the output terminals of the damped oscillation wave, with terminal B grounded; in each branch, the inductor and capacitor are used to adjust the frequency of the output damped oscillation wave, while the damping resistor is used to adjust the damping rate of the damped oscillation wave.
