Study on Optimum Application of Electrolytic Capacitors in Power Supply Equipment

电解电容器以其容量大的特点常用于整流器的平滑滤波、电源的退耦、交流信号的旁路,交直流电路的交流耦合等。本文从分析电容器主要参数性能开始,以整机最佳正确使用为重点,进行比较全面的分析叙述,并提出了一些实用性的经验数据及简图。同时,为进一步提高电子设备的使用可靠性,对电子整机研究、生产单位如何对电解电容器进行验收鉴定、老化筛选、稳定产品性能方面提出一些切实可行的措施。

Electrolytic capacitors , for their large capacitance, are usually used to smooth and rectify current for rectifiers, decouple for power supplies, bypass on couple AC signals. This paper begins with parameters of the capacitors, puts stress on optimum application in electronic equipment, and analyses in all its aspects, gives some experimental tables and drawings. In addition , it raises the measures to check , select, age and stable capacitors, in order to increase reliability of electronic equipment using them.
