一种新型的高功率微波脉冲功率源研究

从微波器件角度提出一种新型脉冲功率源,采用脉冲空心变压器技术路线,通过特殊设计,使初级线圈不仅为次级线圈提供变化磁通,也产生脉冲高压,脉冲高压对脉冲形成线充电,然后产生微波器件需要的电子束,同时初级线圈也可以为微波器件提供相应较强的引导磁场,从而实现脉冲功率源同时为微波器件提供电子束和相应的引导磁场。该新型脉冲功率源可以在一定工作范围内较好地提高脉冲功率源的利用效率,尤其是在小型化结构方面更为明显。

Investigation of a Novel Pulse Power Supply for High Power Microwave

An air core pulse transformer is specially designed to provide the high power electron beam and required magnetic field for the high power microwave device simultaneously. First, the primary coils produce the changing magnet field after the primary capacitor discharges. Then a high voltage pulse is induced in the secondary coils to charge the Pulse Form Line (PFL). The magnetic field produced by the primary coils can keep a very high value when the voltage on PFL reaches the required value (not the highest value). Finally, the main switch is triggered when the required value of the voltage on PFL is reached. So the power supply can provides the electron beam and the required guiding magnet field for microwave device simultaneously when it is properly designed.
