【经验】开关电源直流侧电流纹波估算与电解电容选型

时间： 2019-01-13 来源：世强

技术问答

开关电源直流侧往往需放置电容来滤波，以减少开关电源谐波对前级直流侧（电池、母线等）产生影响。电解电容手册中一般会给出额定纹波电流值（Rated ripple current）。若选择的电容额定纹波电流值过大，则会造成成本甚至体积浪费；而选择过小会造成电容无法承受而损坏。在实际项目中我们往往无法精确获得直流侧阻抗信息以供精密计算，因此需要进行一些估算，帮助我们选择适当的电容额定纹波电流值。

本文以一Buck-Boost电路为例分享如何根据电路进行纹波估算从而合理选型。本文所选电容为世强代理厂牌Nippon Chemi-Con（俗称“黑金刚”）的一款高纹波铝电解电容 EKZN800ELL820MH20D。主电路如下图所示。

图1 主电路图

工作中直流侧电流与流经Q1的电流i相同，它随着Q1的导通、关断而变化。i波形如下图所示。

图2 i波形图

在实际考虑问题时，上图可简化看做方波电流源。

图3 i简化波形图

因此，主电路直流侧可按如下电路图建模分析。

图4 主电路直流侧建模

到这里，我们可以按照直流侧等效阻抗(jwL+R)和直流侧滤波电容1/jwC分流来分析，但我们无从得知直流侧具体的阻抗。所以这里我们做第二个简化——假设方波电流中所有交流量都由电容吸收，而只有直流分量流经直流侧。

于是我们可以进行如下计算。（本电路额定功率为250W。左侧为48V直流母线，右侧为电池40V~58V。记Q1占空比为D）

方波幅值

有效值为

假设电流中所有交流量都由电容吸收，则

故电容上各次谐波分量总有效值为

故D取最小值0.83时，电容纹波有效值最大，为2.33A。故每个电容上纹波电流为1.16A。

考虑到实际上不会全部纹波电流都由电容吸收，所以所选Nippon Chemi-Con的EKZN800ELL820MH20D铝电解电容的抗纹波能力1.04A是满足的。

若仍有担心，可再放一颗薄膜电容，如图1中C8，薄膜电容具有很好的吸收高频能力。以下是实验中电感电流5A（额定功率下运行）测得的直流侧电流纹波为880mA。有兴趣的话还可以根据电感电流纹波和直流侧纹波反推出电容吸收的纹波，并且可以推出直流侧的阻抗信息。

【经验】不同环境温度下，黑金刚铝电解电容使用寿命估算方法

对于出厂检验合格的电解电容，产品合规使用过程中的故障率是很低的，这一安全使用过程也可称为电解电容的寿命。影响电解电容使用寿命的主要因素是环境温度，工作电压和纹波电流，过高的环境温度会引起自身发热，电解液蒸发，氧化膜损坏等，使容量减少、漏电流増大，使电容达不到额定规格。高的工作电压和纹波电流同样会使电容发热，产生同样的后果，使电容寿命下降。本问介绍不同环境温度下黑金刚铝电解电容的寿命估算方法。
