电解电容是一种很常见的电子元器件,电解电容鼓包是电容出现异常的一种现象,硬件工程师们应该都有见过电容鼓包,但电容为什么会鼓包有些工程师就不是很清楚了,今天我们就简单讲讲电容鼓包的原因及使用时的注意事项。


我们知道,电解电容里面是有电解液的,电解液受热时就会产生膨胀,当电解液膨胀到一定程度就会导致电容鼓包,如果电解电容温度升的太快,还可能导致电容爆浆甚至爆炸,所以在使用电解电容的时候,一定要注意电容的温度,而电容的温度主要包括环境温度和温升温度


还有当电容受到浪涌电流或电压冲击时,电解电容的阳极铝箔上的氧化膜受到破坏,这时铝箔中的铝就直接暴露在电解液中,而电解液中是含有水的,所以在阳极的氧化膜破损部分,电解液中的水会和阳极箔(Al)会发生如下化学反应进行修复。


修复后的阳极铝箔上面就会重新覆盖一层氧化膜,并在电容内部产生氢气,当氢气达到一定量的时候,就会导致电容鼓包,所以在使用电解电容时,一定要注意电容的额定电压和额定纹波电流,当实际使用的电压或纹波电流超过电容的额定值,那就会导致电容损坏。


世强目前有供应的铝电解电容品牌有法国的EXXELIA、日本的NCC,国产su’scon和KOSHIN等品牌,其产品广泛使用在汽车电子,工业自动化,UPS,基站、电动汽车,光伏,充电站储能、通信基站设备,IoT,LED照明等应用,其中NCC的HXx系列混合电容和su’scon的SVx系列贴片混合型电容是汽车市场主推产品,产品可靠性高,性能好。

【经验】解析铝电解电容器在新能源领域光伏逆变器产品上的应用

由于光伏发电系统产生的电流为直流电,但民用电力以交流供电为主,且太阳能发电最终将走向并网运行,这就意味着太阳能发电必须通过逆变器将直流电转换为交流电来驱动家用电器等负载。因此,逆变器在太阳能发电系统中具有举足轻重的作用。本文东佳电子为您介绍铝电解电容在新能源领域光伏逆变器产品上的应用。
