摘　　要：为突破能源互联网应用中微波功率对工业应用规模和无线通信距离的限制,开展了基于S波段20 kW磁控管推移特性的两路连续波磁控管功率合成系统实验研究。从理论上分析了20 kW磁控管频率推移特性的功率合成系统的可行性和高效合成条件,从实验中完整表征20 kW磁控管的推移特性,并通过该特性成功实现了双管功率合成。测试结果表明,基于20 kW磁控管频率推移特性的功率合成系统两路合成输出功率为34.0 kW,合成效率为92.3%,合成之后的频率谱有一定改善,为磁控管在能源互联网领域的应用起到了重大推动作用。The microwave power output does not satisfy the requirements for energy Internet because of the increasing industrial processing scale and the modern wireless communication distance.To break through such limitations,an experimental study on two-way 20 kW S-band magnetrons power synthesis system based on frequency pushing is proposed.The feasibilities and condition for high-efficiency power synthesis system are analyzed theoretically,and meanwhile,the pushing characteristics of the 20 kW magnetron are completely characterized in the experiment,and the power synthesis of two tubes is successfully reazlized by this characteristic.The test results show that the synthesized output power of the power synthesis system based on the frequency pushing characteristics of 20 kW magnetron is 34.0 kW,and the synthesis efficiency is 92.3%.The frequency spectrum after synthesis has been improved to a certain extent,which has greatly promoted the application of magnetron in the field of energy Internet.
