摘要
为了使脉管制冷机满足航天的多应用边界需求,提出制冷机压缩机两电机串联驱动方案,对脉管制冷机应用中压缩机电机串联与并联驱动方式进行研究对比。研究表明,压缩机电机由并联驱动改为串联驱动增加了制冷机驱动阻抗,改变了制冷机总驱动电压、电流关系。驱动方式由并联改串联对制冷机效率及探测器电磁干扰无影响,略微改变制冷机自身微振动状态。在制冷机应用时可根据自身电机阻抗与卫星平台提供的电压选择合适的驱动方案,拓展了制冷机应用边界。
In order to make the pulse tube cryocooler adaptable to different voltage provided by the satellite,a series drive method for the two compressor motors is proposed.A comparative research on the series and parallel drive methods of cryocooler’s compressor motors is conducted.The research indicates that when changing the drive method of the compressor motors from parallel to series,the impedance of the cryocooler increases significantly,the relationship between the total driving voltage and current of the cryocooler also changes accordingly.Changing the driving method from parallel to series has no impact on the efficiency of the cryocooler nor the electromagnetic interference to the detector,but slightly changing the micro-vibration of the cryocooler.The appropriate drive mode can be selected based on the voltage provided by the satellite,which expands the application boundaries of the cryocooler.
