DC regulated power supply and leakage protection device based on STM32

The DC regulated power supply and leakage protection device based on STM32 are composed of three parts, which are DC regulated power supply module, leakage protection module and display module. The voltage stabilizing power supply module adopts series voltage stabilizing circuit with amplifying link. The circuit is simple in structure, stable in output voltage and large in output current. The leakage protection device adopts INA195, and the chip can sensitively detect whether the leakage current exceeds the predetermined index. The display circuit uses NOKIA5110 to display the parameters, and realizes the man-machine exchange under the condition of low power consumption and low cost. After testing, the power supply runs stably.
