OBC On-board Charger
The on-board charger (OBC) converts AC from the charging inlet to the traction battery DC bus. It is one of the most thermally demanding subsystems in a passenger EV because it must run at high power in a sealed enclosure with limited airflow.

What OBC On-board Charger power stages need
OBC topologies combine a PFC front end (often interleaved boost) with an isolated DC/DC or LLC stage. Power diodes appear in PFC boost, output rectification and auxiliary rails; SiC Schottky and MOSFET options appear as designers push switching frequency to shrink magnetics. Key selection parameters include VRRM or Vds margin, average and surge current, VF at operating Tj, trr/Qrr for FRD nodes, and RthJC in the actual PCB footprint.
MHCHXM supplies high-Tj Schottky and fast-recovery rectifiers plus SiC diodes suited to OBC voltage classes. Our FAE team helps export OEM and tier-1 programs compare published curves against incumbent parts, request catalog samples (about 48h), and document reliable supplier AVL entries.
