滤波电容的等效电感效应

EQUIVALENT SERIES INDUCTANCE EFFECT OF FILTER CAPACITOR

对DC／DC变换器用状态空间平均法进行了建模分析及PSPICE仿真，讨论了滤波电容的等效串联电感ESL效应对变换器性能和稳定性的影响结果表明，ESL的引入将使变换器增加输出电压的纹波幅度，稳定性也有一定改善．

This paper prescnts modeling of DC/DC converter with the state space averaging method. The anayses and PSPICE simLilation against the buck DC/DC converter is madc. The filter capacitor equivalent series inductance (ESL) has an effect on both performance and stability of the converter. The peoperty of the converter will be improved when medeling for DC oc convertcr by intreducing ESl.
