Hello @CDarrow ,

Infineon portfolio currently contains the reference designs for 400V systems. These designs can be scaled to 700VDC with some design changes. Below recommendations could be shared with the customer and we can support them in scaling the design as per their requirements. 

AC-DC : EVAL_3K3W_TP_PFC_SIC

DC-DC:REF-DAB11KIZSICSYS

The suggested designs could be referred from architecture point of view. The components spec and the qualification can be chosen as per customers requirement.

Additionally, below page contains a detailed walk through of the topologies that could be used on On-board charger application and the component recommendation that fits respective topology.
