This paper summarizes the trend of novel technologies used for electric vehicles (EV) and hybrid electric vehicles (HEV) based on the published papers and reports in order to predict the needs technologies for expanding EV and HEV market. At first, the relationship between energy demand situation and expanding trends of electric propulsion vehicles will be mentioned. Regarding traction motors, required...
This paper presents a front-end converter including a novel bridgeless PFC converter with high reliability and an isolated full-bridge DC-DC converter with a proposed control scheme to improve efficiency under a light load condition. The proposed bridgeless PFC converter can avoid flowing a high inrush current to silicon carbide Schottky diodes and MOSFETs without impairing efficiency. Furthermore,...
