摘要：
Considering that traditional energy storage device of power density and low conversion efficiency greatly limit the electric vehicle handling and performance, a novel DC/DC converter was proposed based on the integrated magnetic structure for hybrid energy storage system in electric vehicles. The results of MATLAB simulation show that adding the second-order Bessel low-pass filter with the filtering performance of the magnetic integrated structure itself, at the same time combining with the advantages of hybrid energy storage system, the efficiency and stability of electric vehicles can be significantly improved. Integrated Magnetic structure can reduce the overall size of converter and decrease the core losses of converter. The hybrid energy storage system composed of storage battery and super capacitor has the characteristics of high capacity energy storage, quick response and recovery of braking energy. The hybrid energy storage system can optimize the power quality, improve the endurance time and acceleration needs of electric vehicles, and has good performance in a typical driving cycle. © 2017, Central South University Press.
