Abstract：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.
