摘　　要：针对目前精密直流电源领域存在的调整精度低、结构复杂和输出直流电不纯的问题,本文提出以STM32单片机为核心控制器,最终实现输出精稳的12V和5V直流电源的方法。该方法首先通过变压器将220V交流电压变换到48V,并通过整流桥后经过两个Buck电路进行斩波;然后使用PID实现对PWM输出波形状态的控制,其中PID的各项参数使用果蝇优化算法(FOA)进行优化;最后对传统的PID算法与果蝇优化算法进行动态特性负载突增和负载突降对比实验,实验结果证明了本文所提方法的有效性。Aiming at the problems of low adjustment accuracy,complex structure and impure output DC power in the field of precision DC power supply,this paper proposes a method to achieve precise and stable 12V and 5V DC power supply with STM32 microcontroller as the core controller.In this method,the 220V AC voltage is first transformed to 48V through a transformer,and then chopped by two Buck circuits after passing through the rectifier bridge.The control of the PWM output waveform state is realized through PID,in which the parameters of the PID are optimized by the fruit fly optimization algorithm(FOA).By comparing the traditional PID algorithm and the fruit fly optimization algorithm,the effectiveness of the method proposed in this paper is proved by the dynamic characteristic load surge and load dump experiments of the output load.
