摘　　要：这里利用AD公司的热电制冷控制器ADN8830设计出高性能、高稳定性的TEC控制电路。该电路通过简单的电容、电阻构成的外部PID(比例积分微分)补偿网络,能够使探测器温度在10 s内稳定在最佳工作点,温度控制精度可达0.01℃。实验结果表明该方案具有效率高、功耗低、体积小等优点,是一种较好的温控设计方案。A Thermo-Electric Cooler（TEC） control circuit of high performance and stability is designed, which is developed by a thermoelectric cooler controller, named ADN8830, produced by Analog Devices Inc. An outside Proportion Integral Differential（PID）compensation network constructed by simple capacitances and resistors, which can make the temperature of detector reach the optimum operating point in 10 s and the precision of this control circuit is 0.01℃. The experimental resuits show that this circuit is a good scheme of temperature control for its high efficiency, low power and compact size.
