電容工作原理種類很多，在不同的工作原理中，所發(fā)揮的作用也有所不同。比如：耦合，濾波、高頻消振、諧振等。但在音響中所用到的電容大部分是為了：濾波、補(bǔ)償、分頻、旁路、和微分。電解電容廠家詳細(xì)介紹下在汽車音響尾箱安裝的大電容又是干什么用的呢？

　　There are many kinds of working principles of capacitors, and their functions are different in different working principles. For example: coupling, filtering, high frequency vibration elimination, resonance, etc. But most of the capacitors used in audio are for filtering, compensation, frequency division, bypass, and differential. So what is the use of the large capacitance installed in the car audio trunk?

　　這種電容容量比較大，都以法拉來計算了，也叫法拉電容，別名雙電層電容、黃金電容、超級電容。這種法拉電容有圓柱形的，也有方形的，方形的都是容量較大的。法拉電容是電化學(xué)性能介于傳統(tǒng)電容和電池的一種新型的 電化學(xué)儲能裝置。

　　This kind of capacitance capacity is relatively large, all in farad to calculate, also known as farad capacitance, also known as electric double layer capacitor, gold capacitor, super capacitor. The farad capacitors are cylindrical or square, and the square ones have larger capacity. Faraday capacitor is a new type of electrochemical energy storage device with electrochemical performance between traditional capacitor and battery.

　　它主要是通過雙電層電容和氧化還原反應(yīng) 產(chǎn)生的法拉第準(zhǔn)電容存儲能量。當(dāng)前，法拉電容的應(yīng)用范圍非常廣泛，尤其是在混合動力汽車方面。

　　It mainly stores energy through electric double layer capacitance and Faraday quasi capacitance generated by redox reaction. At present, farad capacitors are widely used, especially in hybrid electric vehicles.

　　其作為混合動力汽車的電源，可以很好地滿足汽車在啟動、爬坡和加速時對高功率的需求，從而有效地節(jié)約能源并提高電池的使用壽命。

　　As the power supply of hybrid electric vehicle, it can meet the demand of high power when starting, climbing and accelerating, so as to effectively save energy and improve the service life of battery.

　　在汽車音響中，功放釋放大動態(tài)音樂信號的時候，會在極短的時間內(nèi)消耗大量的蓄電池里的電能，從而使電能產(chǎn)生瞬間的真空。

　　In car audio, when the power amplifier releases large dynamic music signal, it will consume a lot of electric energy in the battery in a very short time, so that the electric energy can produce instantaneous vacuum.

　　如果有了這個法拉電容就會恰到好處地釋放其儲備的能量，可以讓功放輸出更穩(wěn)定。

　　If you have this farad capacitor, it will release its reserve energy appropriately, which can make the power amplifier output more stable.

　　電容的好處不僅僅能使汽車音響的功放輸出穩(wěn)定，也能夠讓原車電瓶受益，因?yàn)槠嚨陌l(fā)電機(jī)硅整流到電瓶都沒有濾波的東西，有電容后也確實(shí)能夠讓整車電流得到一個更平穩(wěn)的釋放。

　　The advantages of capacitance can not only stabilize the power amplifier output of the car audio, but also benefit the battery of the original car, because there is no filter from the silicon rectification of the generator to the battery, so the current of the whole vehicle can be released more smoothly with the capacitor.
