Single-stage onboard chargers (OBCs) integrate the two control functions traditionally implemented in two separate stages for power factor correction (PFC) and DC voltage regulation. This integration improves the power density of the system while increasing the control complexity. Traditional phase shift (PS) control, widely applied to two-stage OBCs due to its simplicity, is challenging for single-stage OBCs structure. This paper proposed a compact single-stage bidirectional isolated totempole AC/DC topology with inherent PFC. A novel sinusoidal phase shift control for the proposed topology is presented to achieve high efficiency of up to 96.9% with a high power factor and simple control implementation under a wide output voltage range. A 6 kW SiC-based high-frequency prototype with the global specification is designed. Experimental results verify the expected operation of the proposed structure.
