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(yīng)?
