摘要
采用开关原理与PID补偿技术结合设计了半导体激光温控电源,用于驱动半导体激光器中的半导体制冷片,从而控制激光器的工作温度.由于采用了独特的二次补偿技术,在获得了良好的动态响应性能的基础上,既大大缩小了温控电源的体积,提高了电源转换效率,同时实现了输出电流和电压能够平滑调节而不是脉冲宽度调节,解决了开关电源很难适应温度控制要求的难题,摒弃了不适合温度控制的脉冲宽度调制输出方式.采用新方法设计的电源体积是原来电源体积的10%,输入功率是原有电源的20%,因此这种新的半导体激光温控电源非常适合在激光电视中使用.
A semiconductor laser temperature control power supply is designed, combined with switch mode conversion and PID regulation technology, which is used to drive a TEC（thermoelectric cooler） in the semiconductor Laser ＇Diode for controling its temperature. Due to the use of unique two compensatory technology, firstly we obtain a good dynamic response, and then reduce the volume of the temperature control power supply evidently and improve the conversion efficiency; at the same time the output voltage and current can be regulated smoothly instead of PWM regulation mode, and to solve the problem of switch mode power supply will suit the request of temperature control with difficulty. We discard the PWM output mode which does not suit temperature control. The volume of power supply by the new design way is 10 percent of the primary version and the input power is 20 percent of the primary version, so the new semiconductor laser temperature control power supply is very suitable to being used in laser televsion.
