摘　　要：为满足工程中对超辐射发光二极管(SLD)温度控制电路的低功耗设计需求,提出了一种基于数字脉宽调制(PWM)技术的控制方案,实现了SLD光源温控电路的低功耗设计。实验表明,该温度控制电路功耗低,稳定性高,满足了低功耗设计的工程需求,具有良好的实用价值。To meet the design requirements of low power consumption in the temperature control circuit for superluminescent diode （SLD） , a eontrol scheme based digital PWM technique is proposed, and a low power- consumption design of the temperature control circuit for SLD light source is implemented. Experiments show that the temperature control circuit features low power-consumption, high stability, and can meet the engineering requirements of low power-consumption design, so has good practical value.
