摘要
现在市场上的电源大多还是旋钮电位器调节电压和电流,旋钮电位器会受温度影响对输出的电压,电流产生误差,而且旋钮电位器调节速度慢,定位不准确,存在一次调节不到位的问题,使用起来麻烦,本设计开发的数控移动电源,基于STM32F103VCT6单片机实现数控调节电压,电流,可以实现快速输出设定的电压、电流,转换效率高,过压保护、过流保护,自动休眠,断电记忆等功能。
Most of the power supplies on the market today are knob potentiometers to adjust the voltage and current.The knob potentiometer will be affected by the temperature to the output voltage and current.There will be errors in the knob potentiometer.The adjustment speed of the knob potentiometer is slow and the positioning is not accurate.The problem is that it is troublesome to use.The CNC mobile power supply designed and developed based on the STM32F103VCT6 microcontroller realizes the numerical control of the voltage and current.It can realize the rapid output of the set voltage and current,high conversion efficiency,overvoltage protection,over'current protection,automatic sleep,Power off memory and other functions.
