摘　　要：本文通过对滤波电容纹波的计算和对旁路电容器的分析,说明陶瓷电容有极低的ESR和ESL,能提供较高的性价比,完全可以用于电力电子线路中。新型陶瓷电容在许多开关电源中可以获取和钽电容同等的指标,并达到同样的设计目的。Through calculated the ripple of filter capacitor and analyzed the bypass capacitor, it indicated that ceramic capacitor has extremely low ESR and ESL, provided the high performance-to-price ratio, can be radically applied in electric power electronic circuit. And new-type ceramic capacitor can obtain corresponding performance criteria in many switch powers as well as the Capacitor of tantalum, and achieve the desired purpose of design.
