摘要
分析了电力电子装置中功率因数校正电路输出纹波产生的原因,并给出了理论计算。根据电路的不同用途,分别从纹波、寿命、掉电维持时间等方面给出了电解电容的选型方法,并用产品实例作了详细说明。
The ripple of PFC's output voltage is analyzed. The selection guideline of the electrolytic capacitor is given according to different key targets such as voltage ripple, capacitor's life time and power supply hold-up time. Some products'design examples with experiments illuminate the design progress.
