开关电源用铝电解电容器的失效机理探讨
Failure mechanism of electrolytic capacitors for switch power supply.
【摘要】 研究彩色电视机早返机开关电源用铝电解电容器失效现象及其失效机理,并针对开关电源如何选用铝电解电容器,提出了增加电容器CV积、增强耐纹波能力等建议措施,以减少铝电解电容器在产品中的早期失效。
【Abstract】 ELECTRONIC COMPONENTS & MATERIALS (China), Vol 18, No 6, P 21 22(Dec 1999) In Chinese The mechanism of the electrolytic capacitors for switch power supply in color TV sets are analyzed. Choice of electrolytic capacitors for switch power supply is discussed. The measures are recommended for increasing CV and ripple current capacity to reduce early failure. (3 refs)
