固液混合电容和铝电解电容性能对比研究

Research on Performance Comparison of Solid-liquid Mixed Capacitor and Aluminum Electrolytic Capacitor

本文以商用车EPS为背景,对混合电容和铝电解电容纹波特性和温升特性进行对比研究,结果表明:混合电容具有更小的纹波,且温升明显低于铝电解电容。此研究可为相关产品设计中电解电容的选型提供一定的参考价值。

Based on the background of commercial vehicle EPS,this paper compares the ripple characteristics and temperature rise characteristics of hybrid capacitors and aluminum electrolytic capacitors.The results show that the hybrid capacitor has smaller ripple and the temperature rise is significantly lower than that of aluminum electrolytic capacitors.It can provide a certain reference value for the selection of electrolytic capacitors in the design of related products.
