摘　　要：为满足工程中对光纤陀螺光源控制电路的低功耗、小型化设计需求,设计了一种基于脉冲宽度调制(PWM)技术的光源控制系统。实验表明,该控制系统体积小,功耗低,最大电源效率可达91.4%,全温温控精度可达0.01℃,同时操作灵活,可扩展性强,具有良好的实用价值。To meet the design requirements of low-power consumption and miniaturization control circuit for FOG light source. A light source control system based on pulse width modulation （PWM） technology is designed. Experiments show that the control system has advantage of small in size, low power consumption. Its maximum power efficiency up to 91.4 % ,overall temperature control precision up to 0.01 22. It is flexible for operation and has strong scalability, so it has good practical value.
