摘要
为了提高大功率微波磁控管相干功率合成的效率,并且使合成功率能够长时间稳定输出,需要克服注入锁频磁控管工作时存在的相位漂移问题。基于LabVIEW实现了对两路S波段15k W注入锁频磁控管相干功率合成系统相位的闭环控制。通过对注入锁频磁控管进行移相精度为1.8°的相位控制,使相干功率合成的效率最高达到93.6%,并且保障了相干功率合成系统的稳定。基于LabVIEW的相位闭环控制是微波磁控管相干功率合成系统获取大功率和高效率的关键技术,能够促进注入锁频磁控管在微波能工业中的应用。
It is necessary to overcome the phase drift existing when the injection frequency locking magnetron works in order to improve the synthesis efficiency of coherent powers of large-power microwave magnetrons and realize a longterm stable output.On basis of LabVIEW,the closed-loop phase control on the coherent power synthesis system of twoway S-waveband 15 kW injection frequency locking magnetrons was realized.By carrying out the phase control with 1.8 degrees of phase shift precision for the injection frequency locking magnetrons,the maximum efficiency of the coherent power synthesis can reach 93.6%,in addition,the stability of the coherent power synthesis system can be assured.The closed-loop phase control based on LabVIEW is a key technology for the coherent power synthesis system of a microwave magnetron to obtain large power and high efficiency,it is able to promote the application of injection frequency locking magnetron in the field of microwave energy.
