摘要
介绍了铝电解电容器的主要结构、等效线路和寿命计算公式,着重阐述了铝电解电容在LED灯的常规线路中的主要应用情况。其中针对3种主要应用,详细介绍了铝电解电容的作用、具体应用位置线路、纹波电流值的计算方法,并通过铝电解电容参数特性的分析,给出了相应的选型建议和注意事项。最后通过"加严应用端来料管控"、"加严供方稽查"、"加强应用端考核能力"、"新产品谨慎使用"4个方面的必要性分析,来说明如何更好地推广使用铝电解电容。
In this paper,through the introduction of aluminum electrolytic capacitor,referring to main structure,equivalent circuit and the calculation formula of life,in combination with conventional LED lighting circuit,the main applications of aluminum electrolytic capacitor are elaborated.In the text,the three main applications of aluminum electrolytic capacitor are introduced,about the main effect,the specific application circuit,and the calculation of ripple current value.Then,through analyzing the characteristics of aluminum electrolytic capacitor parameters,the corresponding selection suggestions and considerations are presented.At last,the author explains how to better promote the use of aluminum electrolytic capacitors,through the following necessity analysis,"stricter control about the incoming material","stricter factory audit","to improve the user’s judgment,"careful use of new products".
