分置式斯特林制冷机驱动控制源的抗干扰设计

Anti-jamming design for diven control power of Stirling cryocooler

电磁干扰问题一直是影响斯特林制冷机性能的重要因素,文中分别从硬件和软件两方面对斯特林制冷机驱动控制源的抗干扰设计作介绍。本设计的硬件方面主要采用驱动控制器的输出部分加装LC滤波器、电机的单极性驱动代替传统的双极性驱动和测温部分装光电隔离器等措施;软件部分主要是对采样到的信号进行数字滤波。

Jamming from electromagnetism is an important factor to effect the cahability of Stifling eryoeooler. This paper presented the anti -jamming design for driven and control power of Stirling cryocooler through hardware and software. In hardware we installed LC filter in the output of driven and control power. The monopole control of electromotor replaced the ambipolar control of electromotor and we installed partition of photoelectricity in the part of testing the temperature ete. In software we used the way of digital filtering for the sampled signal.
