- 摘要：基于单片机的数控开关电源是利用单片机实现对开关电源的输出电压设定、输出电压步进调整、输出电压和输出电流显示等数字控制。本文设计的数控开关电源由两部分组成。开关电源部分采用基于PWM控制的不对称半桥功率变换器，由模拟控制芯片KA3525产生PWM信号经驱动电路实现对功率变换电路的输出电压控制，实现电压的稳定输出。数控部分采用凌阳单片机的D/A输出对KA3525的误差比较器的参考端进行数字给定，实现对输出电压的设定、步进调整和显示等功能。文中给出了系统设计框图，对各部分电路进行了分析，并给出了

- 本系统严格按照题中所定参数及要求，构建了一个以MSP430单片机为控制核心的温度自动控制系统。该系统用PSB型负温热敏电阻作为温度传感器，以一种类R-F的方法测量木盒内实时温度，单片机用实时温度与预设温度值一起代入PID算式得出一个温度增量，再用此温度增量线性的控制PWM波的占空比，开关电源的输出电压也会随之变化，即制冷晶片的输入功率发生变化，因此制冷晶片制冷（加热）的功率随PWM波占空比变化，达到自动控温的目的。本系统制冷（加热）效果明显，效率高，界面友好，制作精致，能够胜任题中所定各项要求。
