請(qǐng)問(wèn)各位dx什么是折射電壓?

我在計(jì)算rcd時(shí)候,遇到了次級(jí)到初級(jí)的折射電壓,請(qǐng)問(wèn)什么是折射電壓,如何確定?

I think you are talking about reflected output voltage. It is used in flyback transformer. Why not go to find flyback transformer design method. Lots of articles in this forum.

所謂的折射電壓是根據(jù)電磁感應(yīng)定論﹐電感電流不能突變﹐當(dāng)toff 時(shí)﹐變壓器一次側(cè)的電壓就應(yīng)該是兩者之和﹗
