最近一直在研究spwm正弦波
調(diào)制法設(shè)計(jì)起來(lái)有點(diǎn)繁瑣而且用不上那么精準(zhǔn)，
另一種方法就是規(guī)則采樣法，
現(xiàn)在規(guī)則采樣法關(guān)于矩形波和正弦關(guān)系能懂，
在實(shí)現(xiàn)方向我單純的更趨向于用定時(shí)器模擬輸出時(shí)間用來(lái)控制矩形波的輸出，讓面積與正弦相等。
最近在網(wǎng)上看到很多生成spwm表格的，生成的都是點(diǎn)，比如下面例子，正弦中值128，幅度127，周期取點(diǎn)200點(diǎn)
128,131,135,139,143,147,151,155,159,163,167,171,174,178,182,185,
189,192,196,199,202,205,208,211,214,217,220,223,225,228,230,233,
235,237,239,241,242,244,246,247,248,249,251,251,252,253,253,254,
254,254,255,254,254,254,253,253,252,251,251,249,248,247,246,244,
242,241,239,237,235,233,230,228,225,223,220,217,214,211,208,205,
202,199,196,192,189,185,182,178,174,171,167,163,159,155,151,147,
143,139,135,131,128,124,120,116,112,108,104,100,96,92,88,84,
81,77,73,70,66,63,59,56,53,50,47,44,41,38,35,32,
30,27,25,22,20,18,16,14,13,11,9,8,7,6,4,4,
3,2,2,1,1,1,1,1,1,1,2,2,3,4,4,6,
7,8,9,11,13,14,16,18,20,22,25,27,30,32,35,38,
41,44,47,50,53,56,59,63,66,70,73,77,81,84,88,92,
96,100,104,108,112,116,120,124
但是如果讓定時(shí)器定時(shí)值等于對(duì)應(yīng)的點(diǎn)值，那么輸出的會(huì)是正弦波值嗎？
還是用另一種方式占空比啊？
如有大神看到，望能舉一個(gè)實(shí)例。。。求助
