摘　　要：为了解决微波等离子推力器全系统在真空中进行实验的关键问题 ,减少实验中不必要的能量损失 ,研制出可在大气与真空环境中工作的微波等离子推力器电微波系统 .该系统利用了开关电源、衰减器和检波器一体化设计技术、液体冷却技术 ,解决了微波电子器件在真空中的放电问题 .实验表明 :系统输出的微波功率稳定 。In order to tackle the key problems in the experimental study on the microwave plasma thruster,of which the whole system operates under the vacuum condition,and remove the unnecessary energy loss,an electro-microwave device operating under atmosphere and vacuum condition has been developed by applying the design technology of the nonlinear power supply,the integration of attenuator and detector,liquid cooling,and after resolving the gas breakdown problems of electro and microwave apparatus. The experimental study on the device with argon and helium as propellant has been carried out. The results show that the output power of microwave is stable, the device can operate under vacuum and atmosphere condition reliably.
