Characterize high voltage bi-directional GaN devices.
Design and develop three-phase single-stage wireless power transfer (WPT) system for BMW North America, using 650V bidirectional GaN devices on the grid side. The project will evaluate the merits of bidirectional GaN enabled single stage wireless charging wallbox e.g., lower cost and smaller footprint thereby higher power density.

Promoting the newest bidirectional GaN devices for EV charging applications
