简易数控直流电源
摘要：本实验设计了一个以单片机89C51为基本控制核心的简易数控直流电源。.该设计包括直流电源输入及输出两部分，可完成0~15V之间各不同幅值的电压的输出，能够预置数，能够自动扫描输出电压并直接显示到LED数码显示管上，并可扩展输出三角波等波型。其中电压输出部分，既可手动的每按”+””-”键一下进行每0.1V大小的上下调整，也可长按”+””-”键使其自动的递增或者递减，直到需要的数值。预置数时用切换键切换预置个位或小数位，按”+””-”键进行微调。单片机编程部分是基于WAV

SVPWM的主要思想是以三相对称正弦波电压供电时三相对称电动机定子理想磁链圆为参考标准，以三相逆变器不同开关模式作适当的切换，从而形成PWM波，以所形成的实际磁链矢量来追踪其准确磁链圆。传统的SPWM方法从电源的角度出发，以生成一个可调频调压的正弦波电源，而SVPWM方法将逆变系统和异步电机看作一个整体来考虑，模型比较简单-
The main idea is based on SVPWM symmetrical three-phase sine wave voltage supply thr
