SPWM 计算器 源码，用于查表法，VC#编程，供参考二次开发

生成spwm，其生成的数据可以任意设置 和计算调制比，除此之外不用安装(Generate SPWM, and its generated data can be set arbitrarily And calculate the modulation ratio, in addition, do not instal)

spwm正弦表有很多，但不知怎样调用它，有了这个脉宽计算器 直接调用，不同的定时器频率生成不同的spwm 还附带有定时器周期设置计算值，对正弦波开发很有帮助 (SPWM sine table has a lot of, but I do not know what to call it, the pulse width calculator direct calls, timer frequency of different generation of the SPWM also comes w
