基于单片机的电源变换器，应用升降压电路，使用红外遥控控制输出电压，并带有自动检查，实现自动调节稳压-Power converter based on single chip, application of Buck, use infrared remote control of output voltage, and with automatic inspection, automatic adjustment regulator

07年电赛电源题，单片机发送pwm信号，fpga产生pwm来控制开关管，达到升降压。-2007 power electric race title, the microcontroller pwm signal transmission, fpga generate pwm to control the switch, to buck.

使用stm32系列单片机进行控制。有PID功能，改变基准值，就可以实现升降压。使用12864液晶进行电压、电流值的显示(Use STM32 series singlechip to control. PID function, change the benchmark value, you can achieve the ups and down pressure. Voltage and current values are displayed using 12864 liquid cryst
