F280049使用8組EPWM做相移變頻，PWM動作異常

目前使用F280049做4相全橋(變頻與變duty)的應用，每相都會用到兩組EPWM，所以總共8組EPWM都用完。

目前遇到的問題是4相都要各相差90度，發現在變頻的過程中會發生PWM打出來的不如預期，如下圖所示。

如果將4相設定為同相就沒有問，如下圖所示。

所以看起來是設定相移發生了問題。

1、請問在做相移該需要注意什麼？

2 、我有使用1001的interleaved LLC的global update，一起更新，但似乎問題是一樣的，並且DB無法使用global update更新，所以這也是個問題。

下面是我設定global的程式，不知道是否還少了那些？

Green Deng：抱歉你上传的图片上的信息太少，我不确定你的“不如預期”是指移相的相位角度不对还是移相不成功？或是其他问题？

目前使用F280049做4相全橋(變頻與變duty)的應用，每相都會用到兩組EPWM，所以總共8組EPWM都用完。

目前遇到的問題是4相都要各相差90度，發現在變頻的過程中會發生PWM打出來的不如預期，如下圖所示。

如果將4相設定為同相就沒有問，如下圖所示。

所以看起來是設定相移發生了問題。

回复 Green Deng:

基本上全部的EPWM的頻率都要一樣。

我是做LLC控制

在有問題的部分EPWM5/6的頻率跟duty都不對了。

目前使用F280049做4相全橋(變頻與變duty)的應用，每相都會用到兩組EPWM，所以總共8組EPWM都用完。

目前遇到的問題是4相都要各相差90度，發現在變頻的過程中會發生PWM打出來的不如預期，如下圖所示。

如果將4相設定為同相就沒有問，如下圖所示。

所以看起來是設定相移發生了問題。

1、請問在做相移該需要注意什麼？

2 、我有使用1001的interleaved LLC的global update，一起更新，但似乎問題是一樣的，並且DB無法使用global update更新，所以這也是個問題。

Yang Meng-Chu：請問有人可以協助此問題嗎？

基本上全部的EPWM的頻率都要一樣。

我是做LLC控制

在有問題的部分EPWM5/6的頻率跟duty都不對了。
