The On Board Charger (OBC) uses low on-resistance Si IGBTs or SiC MOSFETs to reduce conversion loss. The on-resistance has the characteristic to drop as the gate voltage rises so it is recommended to design a gate drive circuit using, for example, an Si IGBT with a high voltage of around 15V or an SiC MOSFET with a high voltage of around 18V.
