摘　　要：一种新的光纤光源泵浦源温度控制设计方案被提出来.在该方案中分别设计了测温电路、热电制冷器驱动电路和温度控制逻辑.测温电路采用改进的"桥式"测温电路,降低了电路成本,提高了测温精度.热电制冷器采用专用芯片MAX1968驱动,可以保护元器件.用FPGA实现控制算法,采用数字步进式的控制方法,以提高控制精度,方便系统调试,在此系统的控制作用下,泵浦源温度为0.1℃内,并给出了实验曲线.A new design of temperature control system of pump source for fiber source is presented. The temperature detection circuit, thermoelectric cooler driven circuit and temperature control logic are designed in the scheme. An improved bridge circuit is adopted for the temperature detection circuit so as to reduce the cost and improve precision. The thermoelectric cooler is driven by special MAX1968 to protect the component. The FPGA integrated control logic is combined with digital step control method to improve the precision of control and facilitate debug. Under the control of such system, the temperature variety of pump is stabilized within 0.1℃. At last, the curve of experiment is given in this paper.
