Aiming at the problems of low conversion efficiency,large output voltage fluctuation and inadequate protection mechanisms of traditional power supply modules in industrial process control,this paper proposes a power conversion module that integrates high-efficiency conversion,precise control,multiple protection and intelligent communication functions.This module consists of 12 core units,including a filter circuit and an active power factor correction circuit.It achieves stable output through the collaborative regulation of PWM closed-loop control and MCU,and is equipped with multiple protection functions such as input overvoltage and undervoltage protection,output overvoltage and overcurrent protection,and overtemperature protection.Test results show that the conversion efficiency of this module reaches more than 89%,which is 5%~10%higher than that of traditional power supply modules.The output voltage accuracy is within±3%,and both voltage regulation rate and load regulation rate are≤1%,which is superior to similar products.Various performance indicators of this module meet the requirements of industrial automation control systems for high-reliability power supplies.It can be widely applied to scenarios with strict requirements on power supply stability,such as PLC control and intelligent sensors,and has high practical value and promotion prospects.
