  薄膜电容能用在汽车行业吗?市场上大多数的汽车采用的都是铝电解电容器,随着新能源汽车数量的增加电解电容已经被取代,取而代之的便是薄膜电容

  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.

  薄膜电容器是电动汽车驱动电路中的主要元件,主要起平滑的作用。逆变器将电池的直流电通过转换器转换成变动较小的电压,再通过IGBT开关元件转换成近似于交流电的矩形波,由此产生的浪涌电压很大,需要采用平滑电容器消除。

  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.

  早期的平滑电容器曾采用铝电解电容,但为了提高效率,电机驱动的最大电压从500V提高到了650V后,铝电解电容的耐压不足,薄膜电容器成为主流。

  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.

  未来薄膜电容器在新能源及新能源汽车领域的应用将是主要发展方向。汽车里面一般有三个地方会用到电容器:储能、电机和电控。

  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.

  在新能源汽车电源部分的设计中,需要采用高耐压的电容器进行平滑和滤波的应用,汽车内部通常工作环境恶劣,要求电容器耐高温性能强、可靠性高,寿命长,薄膜电容相比铝电解电容具备较大的优势。

  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.

  从行业属性看,不同于新能源汽车供应链上的其他环节,新能源汽车薄膜电容器行业不存在产能过剩、过度竞争的问题。

  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.
