please answer this question!!!
The mid-time of the clampped mosfet closed between
main mosfet opened how to control.pls make it using NCP1200 or 3842 typical&cheap IC.
thank you expert!!!

這個(gè)和LAMBDA電源的驅(qū)動(dòng)方法是一樣的.
只是LAMBDA用的不是3842

CMG兄,能不能貼一下開(kāi)關(guān)管的波形.
我設(shè)計(jì)的和你的差不多,但波形有些不是太好.

不如直接用高端驅(qū)動(dòng),3580還要變壓器等好多器件
反激的有源嵌位只要不重疊對(duì)時(shí)序要求并不高,用3842加個(gè)高端驅(qū)動(dòng)要簡(jiǎn)單的多吧?
用分離元件也應(yīng)該可以1-2元搞定
