New Combined OBC and LDC System for Electric Vehicles With 800 V Battery

Dae-Woo Lee et al.

Summary: This article proposes a new vehicle charging system (VCS) that combines an on-board charger (OBC) and a low-voltage dc-dc converter (LDC) for electric vehicles with an 800 V battery system. The proposed VCS improves power density by integrating transformers and components, and reduces voltage to limit high voltage generated.
