【Abstract】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.
