The role of compound semiconductors in wireless charging

Regardless of how wireless charging is implemented on our roads, the battery inside every single EV will require power electronics – an area in which compound semiconductors excel.

Wide bandgap compound semiconductors such as silicon carbide (SiC) and gallium nitride (GaN) are already revolutionising the EV industry.

GaN-based wireless power solutions have already been demonstrated to enable higher device placement, spatial freedom, and more extensive air gaps between the transmitter and receiver.

And as GaN has already been used in high-capacity consumer chargers, there is potential to see this replicated in the components used in wireless charging systems on the roads of the near future.
