薄膜電容能用在汽車行業(yè)嗎？市場上大多數(shù)的汽車采用的都是鋁電解電容器，隨著新能源汽車數(shù)量的增加電解電容已經(jīng)被取代，取而代之的便是薄膜電容。

　　Can thin film capacitors be used in automobile industry? Most of the cars on the market are aluminum electrolytic capacitors. With the increase of the number of new energy vehicles, electrolytic capacitors have been replaced, and the film capacitors are replaced.

　　薄膜電容器是電動汽車驅(qū)動電路中的主要元件，主要起平滑的作用。逆變器將電池的直流電通過轉(zhuǎn)換器轉(zhuǎn)換成變動較小的電壓，再通過IGBT開關(guān)元件轉(zhuǎn)換成近似于交流電的矩形波，由此產(chǎn)生的浪涌電壓很大，需要采用平滑電容器消除。

　　Thin film capacitor is the main component of electric vehicle drive circuit, which plays a smoothing role. The inverter converts the DC power of the battery into a relatively small voltage through a converter, and then converts it into a rectangular wave similar to alternating current through IGBT switching elements. The surge voltage generated by this is very large and needs to be eliminated by using a smooth capacitor.

　　早期的平滑電容器曾采用鋁電解電容，但為了提高效率，電機驅(qū)動的最大電壓從500V提高到了650V后，鋁電解電容的耐壓不足，薄膜電容器成為主流。

　　Aluminum electrolytic capacitor was used in the early smooth capacitor, but in order to improve the efficiency, the maximum voltage driven by motor was increased from 500V to 650V, and the withstand voltage of aluminum electrolytic capacitor was insufficient, and thin film capacitor became the mainstream.

　　未來薄膜電容器在新能源及新能源汽車領(lǐng)域的應(yīng)用將是主要發(fā)展方向。汽車里面一般有三個地方會用到電容器：儲能、電機和電控。

　　In the future, the application of thin film capacitors in the field of new energy and new energy vehicles will be the main development direction. There are usually three places in the car where capacitors are used: energy storage, motor and electronic control.

　　在新能源汽車電源部分的設(shè)計中，需要采用高耐壓的電容器進行平滑和濾波的應(yīng)用，汽車內(nèi)部通常工作環(huán)境惡劣，要求電容器耐高溫性能強、可靠性高，壽命長，薄膜電容相比鋁電解電容具備較大的優(yōu)勢。

　　In the design of the power supply part of new energy vehicles, it is necessary to use high voltage resistant capacitors for smoothing and filtering applications. The internal working environment of the automobile is usually bad, which requires the capacitors to have strong high temperature resistance, high reliability and long service life. Film capacitors have greater advantages than aluminum electrolytic capacitors.

　　從行業(yè)屬性看，不同于新能源汽車供應(yīng)鏈上的其他環(huán)節(jié)，新能源汽車薄膜電容器行業(yè)不存在產(chǎn)能過剩、過度競爭的問題。

　　From the perspective of industry attribute, different from other links in the new energy vehicle supply chain, there is no overcapacity and excessive competition in the new energy vehicle film capacitor industry.
