چکیده
This paper presents a modified power factor correction (PFC) ON/OFF control and three-dimensional (3D) printed circuit board (PCB) design for high-efficiency high-power density onboard charger (OBC). By alternately operating one of two boost modules the PFC stage at 50% or less load condition, proposed can reduce load-independent loss stage, such as core capacitor charging switches. It enables OBCs to have high efficiency across wide output range better thermal performance. The 3D-PCB decouples trade-off relationship PCB trace heat spreader design, increasing OBCs. A 3.3 kW prototype composed an interleaved totem-pole bridgeless converter full-bridge (FB) LLC has been built tested verify effectiveness design. 95.7% full (98.2% efficiency) 52 W/in3 density.

متن کاملInductor Design Method of DCM Interleaved PFC Circuit for 6.6-kW On-board Charger
Because the on-board charger (OBC) is installed in electric vehicles (EVs), high power density is regarded as a key technology. Among components of the OBC, inductors occupy more than 30% of the total volume. Thus, it is important to reduce the volume and the weight of inductors while maintaining thermal stability. Discontinuous conduction mode (DCM) can satisfy these requirements; however, onl...
