Design of High Performance DC Power Supply Based on STM32
A high precision,high efficiency and wide output programmable DC voltage regulator power supply based on synchronous rectifier Buck circuit is designed.The digital power controller STM32F334 is selected as the MCU for this power supply.The signal conditioning circuit is designed with differential amplifier circuit,and the sampling parameters are linearly corrected.Further improve the output accuracy and dynamic performance of the power supply.At the same time,the power supply has short circuit,over voltage,over current,over temperature protection functions.Through testing and verification,the DC voltage regulator design can achieve 0～48 V wide voltage output,the output ripple is less than 50 mV,the conversion efficiency is 94%,the maximum output power is 450 W,the protection function is complete,and the output accuracy,con-version efficiency,output range,reliability and safety of the programmed DC voltage regulator power supply are improved.
