| Abstract |
In this paper, different high frequency inductors for a DC-DC converter for electric vehicles aredesigned and compared. The interleaved bidirectional DC-DC converters are good candidates to boostthe battery pack voltage to the required voltage level, so that the traction inverters operate in anefficient manner. The use of wide bandgap devices allow to decrease the passive component size, asthe switching frequency is increased. Nevertheless, the different high frequency effects need to becarefully analyzed.Different high frequency inductors are designed and compared at a target switching frequency of 0.5-1 MHz and a maximum power of 5 kW. For this purpose, different core materials, shapes and windingconcepts are considered. An analytical and simulative analysis is first realized and then, the selectedinductors are prototyped and tested using a laboratory platform. |
