本發明涉及電(dian)源(yuan)，特(te)別涉及一種零(ling)壓降無反(fan)灌的雙(shuang)電(dian)源(yuan)自動切(qie)換電(dian)路。

背景技術：

1、隨著電(dian)子技術的(de)(de)發展，有些應用(yong)(yong)場景需(xu)要使用(yong)(yong)到雙(shuang)電(dian)源電(dian)路(lu)，比如智能(neng)馬(ma)桶上的(de)(de)沖洗系統電(dian)路(lu)，當停電(dian)時，啟動備(bei)用(yong)(yong)電(dian)源進行沖洗。雙(shuang)電(dian)源切換(huan)會存在壓降及(ji)反灌現象，導致轉(zhuan)換(huan)效率(lv)低下，能(neng)量損耗等問題(ti)，因此(ci)需(xu)要設計零壓降且(qie)無反灌的(de)(de)雙(shuang)電(dian)源自動切換(huan)電(dian)路(lu)。

技術實現思路
