| Abstract: | Two types of Digital Control Driven Sources of Stirling Cryocooler was introduced in this paper. We analyzed the interference to the infrared chips caused by single polar driving and double polar driving and compared the advantages and disadvantages of two driven sources. The advantages of digtal filtering technology, PID control arithmetic was detailed in this paper. The advantages of V/F conversion circuit was also presented. |
