復(fu)位電(dian)(dian)(dian)路中，放電(dian)(dian)(dian)鉭(tan)(tan)(tan)電(dian)(dian)(dian)容(rong)確不(bu)(bu)可缺(que)少。當電(dian)(dian)(dian)源斷電(dian)(dian)(dian)后，鉭(tan)(tan)(tan)電(dian)(dian)(dian)容(rong)經過鉭(tan)(tan)(tan)電(dian)(dian)(dian)容(rong)D敏捷(jie)放電(dian)(dian)(dian)，待電(dian)(dian)(dian)源康復(fu)時(shi)便可完(wan)成可靠上電(dian)(dian)(dian)主動(dong)復(fu)位。若沒有鉭(tan)(tan)(tan)電(dian)(dian)(dian)容(rong)D，當電(dian)(dian)(dian)源因某種攪擾瞬間斷電(dian)(dian)(dian)時(shi)，因為鉭(tan)(tan)(tan)電(dian)(dian)(dian)容(rong)不(bu)(bu)能(neng)敏捷(jie)將電(dian)(dian)(dian)荷放掉(diao)，待電(dian)(dian)(dian)源康復(fu)時(shi)，單片機不(bu)(bu)能(neng)上電(dian)(dian)(dian)主動(dong)復(fu)位，導(dao)致程序運轉(zhuan)失(shi)控。電(dian)(dian)(dian)源瞬間斷電(dian)(dian)(dian)攪擾會導(dao)致程序住手正常運轉(zhuan)，形成程序或進入死循環。

若斷電攪擾脈沖較寬，可以使RC鉭電容敏捷放電，待電源康復后經過上電主動復位，使程序進入正常狀況;若斷電攪擾脈沖較窄，斷電瞬間RC鉭電容不能充分放電，則電源康復后體系不能上電主動復位。avx鉭電容開關電路作為一種被廣泛應用在開關電路模式，其自身具有規劃簡略、工作穩定等特性。但是，在實踐運用中，工程師也需要依據環境要求，對三極管開關電路進行相應的改進，使其愈加合適規劃條件的需要。在今天的文章中，我們將會為我們分享一些比較常常用到的開關電路改進措施。
