数控直流电源的一种实现方法

A kind of Realization Way of the Digital DC Source

本设计运用单片机来实现智能控制,利用放大电路和CW 317电路来实现电压和电流的放大,可实现0-20 V输出,最大输出电流2 A。最后运用ADC0809对输出电压进行反馈,以实现稳压输出。

This design realizes the intelligent control using MCU, and then realizes the voltage and the current enlargement using the enlargement circuit and the CW317 circuit, it may realize the 0V - 30V output, 2A maximum output current. Use ADC0809 to feedback the voltage of outputting finally, in order to realize that the steady voltage is exported.
