Definitions
- the invention relates to a high-power generator for generating a broadband electromagnetic pulse with a magnetic coil flow compressor comprehensive Pulse generator and a pulse generator downstream of the pulse generator.
- Such a high-performance generator is known for example from DE 195 28 112 C1.
- This is a means of a bullet in a target area be moved High-power microwave generator for combating electronic equipment whose Pulse generator a power supply unit (battery with capacitive storage) with a downstream magnetic flux compressor.
- the corresponding, am Output of the magnetic flux compressor resulting current pulse is at this known high-power generator for pulse shaping an RF tube, preferably a Magnetron supplied, which in turn with an antenna for radiating the corresponding Störpulses is connected.
- From DE 199 59 358 A1 is also a high-performance generator for non-lethal destruction, Fault or glare electronic equipment known in which the pulse generator for further increase in voltage downstream of the magnetic flux compressor, based on exploding wires based opening switch.
- Pulse shaping is in this high power generator, a cable pulser for generating a polar or bipolar rectangular pulse used, which then a suitable Broadband antenna is supplied.
- the invention is based on the object, a high-power generator of the above specify the type mentioned, which generates a pulse of high energy, which is a broad, preferably has up to the microwave range reaching frequency spectrum, wherein in the energy spectrum, the high frequencies compared to comparable well-known high-power generators have a higher energy.
- the invention is based essentially on the idea that as a pulse shaper a Oscillating circuit arrangement with at least two series-connected parallel resonant circuits different resonant frequency is used, the two resonant circuits via at least one non-linear ferrimagnetic coupling member coupled together are.
- nonlinear coupling member especially a tubular or rod-shaped Ferrite core (core of a ferrimagnetic ceramic material) with substantially Rectangular hysteresis loop proved to be advantageous to the coils of the two Enclose resonant circuits.
- the designated in Fig. 1 by 1 high-power generator comprises a pulse generator 2, a electronic control device 3 and a pulse shaper 4.
- the pulse shaper is a broadband antenna 5 (e.g., a spiral antenna).
- the electronic one Control device 3 connected sensor 6 for receiving external signals provided.
- the per se known pulse generator 2 comprises a battery consisting of energy source 7, whose voltage in a semiconductor converter 8 to one for charging a capacitive Memory 9 required value is increased, a magnetic coil flux compressor 10, a e.g. by opening wires formed by exploding wires 11 and one of the opening switch downstream discharge device 12 (e.g., a high pressure spark gap) to increase the steepness of the rising edge of acting on the pulse shaper 4 Pulse (the rise time of the pulse should be ⁇ 1 ns).
- the pulse shaper 4 consists essentially of a resonant circuit arrangement with at least two series-connected parallel resonant circuits 13, 14 different Resonant frequencies.
- a non-linear coupling of the oscillating circuits 13, 14 by means of a rod or tubular ferrite core 15 (in Fig.2 by a dashed line Line indicated), which has an approximately rectangular hysteresis loop, and the is surrounded by the inductors of the resonant circuits 13, 14 forming coils.
- the sensor 6 receives an external signal (e.g., reception of the characteristic characteristic of a target) Signal), this activates the electronic control device 3. This generates then a switching signal, through which the power source 7 to the semiconductor converter. 8 connected and the capacitive memory 9 is charged.
- an external signal e.g., reception of the characteristic characteristic of a target
- the wires in the opening switch 11 explode.
- the electrical resistance of the opening switch 11 increases. This leads to a rapid increase of the voltage across the opening switch 11.
- This voltage is applied the downstream discharge device 12 at.
- the discharge device 12 causes a further increase in the slope of the pulse (and thus a shift in the upper end of the frequency spectrum to higher frequencies).
- the extremely high current pulse generated by the pulse generator 2 with a steep rising edge then acts on the resonant circuit arrangement of the pulse shaper 4, which substantially consists of the two mutually coupled parallel resonant circuits 13, 14.
- the parallel resonant circuits 13, 14 via a ferrite core with rectangular hysteresis loop are coupled together cause the current oscillations in the resonant circuits 13, 14 a sequential switching of the ferrite core 15 from its initial state in the saturation state, back to the initial state and again in the saturation state etc.
- the coupling factor between the oscillating circuits 13, 14. leads to an overlap of their resonance bands and, as a result, a broadening of the spectrum of the resonant circuit arrangement.
- the upper limit of the excited oscillation spectrum by the Resonant frequency of the ferrite core 15 determined.
- L g (t) again denotes the time-dependent inductance of the coil of the magnetic flux compressor 10.
- C 1 and C 2 form the capacitances of the double resonant circuit, L 1 and L 2, the inductances, R 1 , R 2 and R g (t), the resistances of the inductors L 1 , L 2 and L g (t).
- R s (t) the temporal behavior of the opening switch 11 is described.
- R M (t) describes the temporal behavior of the discharge device 12.
- a total of three oscillating circuits have formed: a resonant circuit consisting of the inductance L g (t) of the magnetic flux compressor 10 and the capacitances C 1 and C 2 and the two resonant circuits denoted by 13 and 14.
- Each of these three resonant circuits has its own resonant frequency, whereby the resonant frequencies change with time.
- the resonance frequency of the resonant circuit consisting of the inductance L g (t) and the capacitors C 1 and C 2 changes due to the temporal change of the inductance L g (t).
- the two resonant circuits 13 and 14 change their resonance frequencies due to the coupling via the ferrite core 15.
- the coupling of the broadband antenna 5 to the double resonant circuit 13, 14 may alternatively such that the respective input resistance of the antenna 5 parallel to the double resonant circuit 13, 14 ( Figure 2) or in series with the double resonant circuit 13, 14 ( Figure 3) is arranged.
- the coupling may be e.g. inductively (FIG. 4).
- at a serial arrangement of the input resistance of the antenna 5 may be provided that the input resistance only after the oscillation of the double resonant circuit 13, 14th can be switched by means of a switching device 16 ( Figure 5).
- the invention is not limited to the embodiments described above limited.
- to "smooth" the frequency spectrum Also more than two resonant circuits can be used.
- the choice of resonance frequencies the resonant circuits and the nonlinear coupling means, and thus the position and shape of the Frequency spectrum, depends on the particular purpose of the high-performance generator.
- the upper limit of the frequency spectrum is not in the GHz, but in the MHz range lie, so may be on a device to increase the steepness of the pulse generator generated pulse can also be dispensed with.
- the high-performance generator according to the invention can be very compact and is Therefore, especially for installation in bullets for the lethal destruction of electronic However, it can of course also in civilian areas, such as the Space technology.
