【Abstract】 With the improvement of social environmental awareness, electric vehicles(EV) and hybrid electric vehicles(HEV) are becoming more and more popular in the global market. On-board power system is one of the important components of electric vehicle. The selection and design of ferrite magnetic materials and devices play an important role in the high power, small volume, light weight, low cost and high efficiency of on-board power system. This paper combs the recent research results of circuit topology of on-board power system, and extracts the ferrite magnetic materials,transformers and inductors used in on-board power system, so as to provide reference for the R&D and production of ferrite magnetic materials and devices.更多还原
