专利汇可以提供Apparatus and method for radio-frequency pulse generation in tuned radio-frequency loads专利检索，专利查询，专利分析的服务。并且This disclosure describes a radio frequency (RF) pulse generation system employing magnetic pulse compression circuits coupled through individual matching transformers into a tuned RF load. The pulse compression circuits are operated sequentially, and each circuit is matched to the tuned load the impedance of which (volt-ampere relation) is a function of the current amplitude during the generation of fast rising pulses. Variations in amplitude, pulse width and position of each half-cycle current pulse are obtained by control of the corresponding magnetic pulse compression circuit.，下面是Apparatus and method for radio-frequency pulse generation in tuned radio-frequency loads专利的具体信息内容。

权利要求

1. Radio-frequency pulse generation apparatus having, in combination, a plurality of sequentially operated energy storage and discharge and magnetic pulse compression circuits for generating successive fast-rising pulses, a common tuned load the impedance of which varies with the current amplitude during the generation of said pulses, a plurality of coupling transformer circuits, one corresponding to each of the pulse compression circuits and connecting the same to said common tuned load, the pulse compression circuits being provided with respective switching means for sequentially discharging the stored energy producing pulse compression and transmitting the same through the corresponding coupling transformer circuits into the tuned load.

2. Apparatus as claimed in claim 1 and in which the said coupling circuits each include a series-resonance network.

3. Apparatus as claimed in claim 1 and in which the said coupling circuits each include a weak magnetic coupling.

4. Apparatus as claimed in claim 1 and in which the said coupling circuits each include both a series-resonance network and a weak magnetic coupling, and further switching means is provided to remove the series-resonance network from effective operation when the current in the generated pulses reaches a value of substantial equality for each of the series-resonance and weak magnetic couplings.

5. Apparatus as claimed in claim 1 and in which each energy storage circuit is provided with its own source of DC supply voltage.

6. Apparatus as claimed in claim 1 and in which each energy storage and discharge circuit comprises a pair of cascaded charging circuits each having series inductances and SCR switches and parallel capacitors, and each corresponding maGnetic pulse compression network comprises saturable reactor means series-connected between the charging circuits and their corresponding coupling transformer circuit.

7. Apparatus as claimed in claim 6 and in which means is provided, responsive to the triggering of said SCR switches, for saturating the corresponding saturable reactor means and thereupon discharging the energy charged in said charging circuits into the tuned load through the corresponding coupling transformer circuits.

8. Apparatus as claimed in claim 1 and in which further switching means is provided shunting the coupling transformer circuits and operable when the peaks of the said pulses are sequentially reached to cause the tuned load thereupon to ring down.

9. A method of radio-frequency pulse generation, that comprises, storing energy at a plurality of locations and sequentially discharging the same, magnetically compressing each such discharge to generate corresponding sequential compressed output pulses, coupling said output pulses to a tuned load, and shunting out said coupling when the peaks of said output pulses are sequentially reached, thereby causing the tuned load thereupon to ring down.

10. A method as claimed in claim 9 and in which said coupling is series resonated for relatively low output pulse currents and weakly coupled for relatively high output pulse currents.
