SVPWM
- 为了避免复杂的三角函数和求根运算,便于数字信号处理器的实时运算,提出一种新 的SVPWM算法。采用SPWM中调制波与载波相比较的规则采样思路,通过在静止坐标系下直接 计算每个参考电压矢量所对应的三相调制波的函数值,进而得到每相电压在一个PWM周期中的 占空比.该算法的主要特点是计算简单,只需要普通的四则运算,适用于数字化系统。在扇区划 分和占空比饱和的处理上较传统SVPWM算法更简便,且过调制范围也略有拓展,具有很大的实 用性。仿真和实验结果证实了该算法的有效性。-In or

- 从经纬度BL换算到高斯平面直角坐标XY(高斯投影正算),或从XY换算成BL(高斯投影反算),一般需要专用计算机软件完成,在目前流行的换算软件中,存在一个共同的不足之处,就是灵活性较差,大都需要一个点一个点地进行,不能成批量地完成,给实际工作带来许多不便。笔者发现,用EXCEL可以很直观、方便地完成坐标换算工作,不需要编制任何软件,只需要在EXCEL的相应单元格中输入相应的公式即可。下面以54系为例,介绍具体的计算方法。-BL translated from latitude and longit
