經(jīng)常會要求輸出正負對稱無直流分量的波形，因為直流不不攜帶信息（直流也可以攜帶信息，但相對于交流攜帶信息太少），而且還會增加系統(tǒng)的功耗或者導(dǎo)致系統(tǒng)飽和。舉個例子：我們用的DA芯片基本都是單極性的，只能輸出正值0V以上的波形，那么怎么變成正負對稱的呢？全部是單電源的系統(tǒng)怎么輸出雙極性的波形呢？如下圖所示，選擇一個合適的隔值電容C1串連在系統(tǒng)中，就可以解決這些問題。通常隔直電容容值都比較大，那么到底有沒有一個明確的選擇標準呢？當(dāng)然還是有的，隔直電容需要根據(jù)頻率和負載電阻來選擇。如果你仔細觀察的話，隔直電容和負載電阻其實還是構(gòu)成了一個分壓網(wǎng)絡(luò)，可以歸類到高通濾波器。在濾波電容那里我們得到一個結(jié)論就是當(dāng)電阻的阻抗等于電容的阻抗的時候，剛好在通帶的截止頻率處，此時，我們這里只是想把直流分量去掉，對交流分量不作衰減，因此需要讓電容的阻抗遠小于電阻的阻抗，這樣交流信號在負載電阻上分到的電壓就遠大于電容上的電壓，即需要的交流電壓全部加在負載上，此時交流分量。知道了怎么利用電容把非對稱的波形變成對稱的了之后，反過來怎么給對稱的波形，加一個直流分量呢？這里的電容C1也叫做耦合電容。嘉興防護電容器零售價AAMR電容器質(zhì)量哪家好，歡迎來電咨詢，無錫市錫容電力電器有限公司。</p><div

任何儲能到10焦耳的電容器即有危險性，若儲能到50焦耳以上，有可能會致命。電容器可能在放電后幾分鐘，還有其原始電量的1%至20%，因此一個看似安全的電容器其實可能具有相當(dāng)?shù)奈ｋU性。（8）漏電流漏電流（Leakage）可以等效為在電容器上并聯(lián)一個電阻。電容器暴露在高溫下，可能會破壞其介電質(zhì)，造成過量的漏電流，這是早期真空管電路常見的問題，特別是使用油浸紙電容器或是金屬箔電容器的情況。在許多真空管電路中，會用級間耦合電容器來將變動的信號從真空管的一極到下一級的柵極電路。漏電流大的電容器會讓柵極電壓較其正常設(shè)定值要高，產(chǎn)生過大的電流，或是讓下一級真空管的信號扭曲。若是功率級真空管，甚至?xí)寲艠O板發(fā)紅，或是讓限流電阻器過熱，甚至于失效。在固態(tài)（晶體管）放大器中仍有類似考量，不過因為發(fā)熱較真空管要少，而且使用現(xiàn)代的聚酯電介質(zhì)材質(zhì)作為屏障，這種問題已經(jīng)比較少見。（9）長久未使用后的失效鋁電解電容器供應(yīng)商在制造電容器時，會提供足夠的電壓，使其內(nèi)部處于適當(dāng)?shù)某跏蓟瘜W(xué)狀態(tài)下，提供電壓的步驟稱為活化（conditioned）。有電解電容器的電路若正常使用，會讓電容維持在活化狀態(tài)下，若有電解電容器的電路長期沒有通電，需要重新活化。</p><p>

一工作原理：電容器與電池類似，也具有兩個電極。在電容器內(nèi)部，這兩個電極分別連接到被電介質(zhì)隔開的兩塊金屬板上。電介質(zhì)可以是空氣、紙張、塑料或其他任何不導(dǎo)電并能防止這兩個金屬極相互接觸的物質(zhì)。電容器上與電池負極相連的金屬板將吸收電池產(chǎn)生的電子。電容器上與電池正極相連的金屬板將向電池釋放電子。充電完成后，電容器與電池具有相同的電壓（如果電池電壓是，則電容器電壓也是）。二主要用途：1.電容器用于存儲電量以便高速釋放。閃光燈用到的就是這一功能。大型激光器也使用此技術(shù)來獲得非常明亮的瞬時閃光效果。2.電容器還可以消除脈動。如果傳導(dǎo)直流電壓的線路含有脈動或尖峰，大容量電容器可以通過吸收波峰和填充波谷來使電壓變得平穩(wěn)。3.電容器可以阻隔直流。如果將一個較小的電容器連接到電池上，則在電容器充電完成后（電容器容量較小時，瞬間即可完成充電過程），電池的兩極之間將不再有電流通過。然而，任何交流電流(AC)信號都可以暢通無阻地流過電容器。其原因是隨著交流電流的波動，電容器不斷地充放電，就好像交流電流在流動一樣。4.電容器與電感器一起使用，可構(gòu)成振蕩器。溫州低壓電容器廠</p><p
