Description

Technical Field

[0001] This invention belongs to the field of power electronic device application technology, specifically relating to a primary and secondary integrated system-level interference generator device with controllable triggered discharge. Background Technology

[0002] Most existing high-frequency damped oscillation wave generators use a method of charging energy storage capacitors to store energy and controlling the opening and closing of high-frequency electronic switches to release energy onto a resonant LC load, thereby outputting the desired damped oscillation wave. This method can only output a single damped oscillation wave and cannot be superimposed on a power frequency voltage. In addition, due to the technical limitations of electronic switches, it is difficult to generate damped oscillation waves above 10kV using a series-parallel connection scheme of electronic switches. Furthermore, existing primary-side interference simulation devices are mostly large-scale outdoor test devices, which are bulky, cumbersome to operate, and have difficult-to-control interference waveform parameters. 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 with controllable trigger discharge, which addresses the shortcomings of the prior art and solves the technical problem that it is impossible to use a small-volume device to output superimposed attenuated oscillating wave interference of power frequency.

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

[0005] A primary and secondary fusion system-level interference generator device with controllable triggered 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 via a current-limiting inductor. The N terminal of the power frequency AC power supply is connected to a ground wire. The H terminal of the adjustable gap is connected to the C terminal of a series resonant load group. The D terminal of the series resonant load group is connected to the N terminal of the power frequency AC power supply and the ground wire, respectively. The C and D terminals of the series resonant load group serve as primary interference waveform output terminals. The G and P terminals of the adjustable gap are connected to a controllable triggering device to provide trigger pulses.

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

[0007] Furthermore, the series RLC resonant branch includes a capacitor Cn. One end of the capacitor Cn is connected to the C terminal of the series resonant load group via a disconnecting switch Sn. The other end of the capacitor Cn is connected to the D terminal of the series resonant load group via a resistor Rn and an inductor Ln in sequence.

[0008] Furthermore, terminals A and B of inductor Ln serve as the output terminals for the secondary-side damped oscillation interference waveform, with terminal B grounded.

[0009] Furthermore, the series RLC resonant branch includes at least three branches.

[0010] Specifically, the controllable triggering device includes a microcontroller connected to an ST transistor. The common terminal of the ST transistor is connected to one end of the primary inductor of the pulse transformer via a capacitor CP. The other end of the primary inductor of the pulse transformer is connected to the normally open terminal of the ST transistor. One end of the secondary inductor of the pulse transformer is split into two paths via a diode D1 and a thyristor SW. One path is connected to one end of the primary inductor of the isolation pulse transformer via a capacitor C5, and the other path is connected to the other end of the primary inductor of the isolation pulse transformer via an inductor and a diode D2. The other end of the primary inductor of the isolation pulse transformer is connected to both the thyristor SW and the other end of the secondary inductor of the pulse transformer.

[0011] Furthermore, capacitor CP is connected to AC220V via an AD-DC switching power supply, and AC220V is converted to high voltage HV via an AD-DC switching power supply and connected to capacitor C5.

[0012] Specifically, the gap breakdown voltage of the adjustable gap is 5–10 kV.

[0013] Specifically, the rated charging voltage of the power frequency AC power supply is 25-50kV.

[0014] Specifically, the interference generator can generate a 10kV 3-10MHz bipolar attenuated oscillation interference wave and a power frequency AC waveform superimposed with a 10-50kV high-frequency attenuated oscillation interference wave.

[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 with controllable trigger 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. In addition, the device can output a power frequency AC waveform with superimposed high-frequency interference to simulate primary side electromagnetic interference.

[0017] Furthermore, the series resonant load group includes multiple series RLC resonant branches, which are connected in parallel to achieve frequency adjustment of the superimposed attenuated oscillation wave interference.

[0018] 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.

[0019] Furthermore, terminals A and B of the inductor Ln serve as the output terminals of the secondary-side damped oscillation interference waveform to output a single damped oscillation wave based on ground potential.

[0020] Furthermore, the number of series RLC resonant branches can be changed as needed to make the device more streamlined.

[0021] Furthermore, the controllable triggering device makes gap breakdown more controllable and improves the stability of the output waveform.

[0022] Furthermore, the AD-DC switching power supply can generate a high DC voltage to produce a high voltage trigger pulse while using the same 220V power supply.

[0023] Furthermore, the adjustable gap can be used to adjust the amplitude of the secondary side attenuated oscillation interference waveform by adjusting the distance of the adjustable gap.

[0024] Furthermore, the power frequency AC power supply adjusts the amplitude of the output voltage.

[0025] In summary, this invention avoids the technical difficulties associated with series and parallel connection of electronic switches, and can output high-amplitude repetitive interval decaying oscillation waves; in addition, it can output power frequency AC waveforms superimposed with high-frequency interference to simulate primary side electromagnetic interference.
