Abstract :
This paper presents the design of an auxiliary power distribution network for an electric vehicle. Efficiency is a key element in the design for any electric vehicle and a 48 Vdc distribution network will be used throughout the vehicle. The high efficiency Cuk converter has been selected as the most appropriate topology to supply the various distributed loads. To achieve the best compromise between efficiency and component sizes, a switching frequency of 100 kHz is used. The results from simulations and experimental measurements are discussed and a range of proposals is also made to modify some of the existing loads to further improve efficiency
