【Abstract】 Based on the analysis to the thermoelectric cooler driving principle and its characteristics, This paper proposes a design for a high precision miniaturized PWM temperature controller circuit. The circuit mainly is applied on a 320X240 UFPA (Uncooled Focal Plane Arrays) infrared detector, it can increase the accuracy by restricting the local temperature of crucial sense organ to a narrow range. Appropriate applications for this approach include fiber optic laser module, photon amplifier, precision miniaturized black body and high-performance crystal-oscillator.更多还原
