薄膜電容器被人們稱之為塑料薄膜電容,主要是以塑料薄膜來作為電介質(zhì)的。由于電容器的電質(zhì)不同,它的種類也非常的多。如電解質(zhì)電容,空氣電容,紙質(zhì)電容和薄膜電容等。
Thin film capacitor is called plastic film capacitor, which mainly uses plastic film as dielectric. Due to the different electrical quality of capacitors, there are many kinds of capacitors. Such as electrolyte capacitor, air capacitor, paper capacitor and film capacitor.
薄膜電容器主要是以金屬箔來當(dāng)電極,然后通過電能來工作的。由于它本身具有著很多優(yōu)良的特性,所以是一種優(yōu)良的電容器,就像理工上常見的知識(shí)特性,無極性,絕緣阻抗能力好等。所有,很多的模擬電路會(huì)選用它,且安全可靠,能減少對(duì)人們本身的危害。
Thin film capacitor mainly uses metal foil as electrode, and then works through electric energy. Because it has many excellent characteristics, it is an excellent capacitor, just like the common knowledge characteristics in science and engineering, such as non polarity, good insulation impedance, etc. All, a lot of analog circuits will choose it, and safe and reliable, can reduce the harm to people themselves.
除了用作電路,薄膜電容器的用處還是非常多的,像電子,家里的電器,電話,電氣等多個(gè)行業(yè)領(lǐng)域都能看到它們的身影,很多人每天都接觸著這些東西,而卻不知道它就是薄膜電容器制成的。
In addition to being used as circuits, film capacitors have many uses, such as electronics, home appliances, telephone, electrical and other industries. Many people contact these things every day, but they don't know that they are made of thin film capacitors.
薄膜電容器的使用范圍是十分廣泛,例如空調(diào),冰箱,洗衣機(jī),風(fēng)扇,電源等等。薄膜電容器也涉及了交通運(yùn)輸行業(yè),我們熟悉的動(dòng)車也有薄膜電容器的身影。薄膜電容器的主要應(yīng)用領(lǐng)域有哪些?
Film capacitors are widely used, such as air conditioners, refrigerators, washing machines, fans, power supplies and so on. The film capacitor also involves the transportation industry, we are familiar with the EMU also has the film capacitor figure. What are the main applications of thin film capacitors?
1)在電力電子線路中的應(yīng)用。薄膜電容器它被使用在該處,主要就是起著電力電流的一個(gè)緩沖以及箝位、諧振旁路以及抑制電源電磁的干擾等等作用。
Application in power electronic circuit. Thin film capacitor, which is used here, mainly serves as a buffer and clamp of power current, resonance bypass and suppression of electromagnetic interference of power supply.
2)當(dāng)薄膜電容器用作旁路時(shí),它主要就是起著降低直流母線的阻抗以及吸收來自負(fù)載的紋波電流,從而起到有效地抑制直流母線電壓在因負(fù)載突變而出現(xiàn)的波動(dòng)。
When thin film capacitor is used as bypass, it is mainly used to reduce the impedance of DC bus and absorb the ripple current from load, so as to effectively suppress the fluctuation of DC bus voltage due to load mutation.
3)當(dāng)該裝置用于諧振式變換器時(shí),它就能夠起到與電感一起實(shí)現(xiàn)諧振的功能。
When the device is used in resonant converter, it can realize resonance with inductor.
不不同的應(yīng)用領(lǐng)域中,薄膜電容器發(fā)揮著不同的作用,只有了解薄膜電容器的工作原理才能在使用的時(shí)候更加的游刃有余。
In different application fields, thin film capacitor plays a different role. Only by understanding the working principle of thin film capacitor can we be more comfortable when using it.
