為什么通常我們認為phase點電壓尖峰隨著負載增大而增大?我的分析如下?請大家指正。
My analysisfor”why does customer think Vsw will increase when load more”
Usually, we thinkthe Vsw oscillation is caused by stray inductor and rectification mosfet’s bodydiode reverse recovery performance, so Vsw=Vin+Ls1*Irr/ts. the diode junctiontemp will increase when load more, and then it's Irr/ts will increase whichleads to higher Vsw.
對了,我怎么無法把圖貼上來啊?好像無法直接copy圖及進來。按照下面的說明操作,但是點擊“插入編輯器”后無任何反應?
