Silicon Carbide MOSFETs from ROHM selected by Lucid

ROHM Semiconductor has said in its release that electric vehicle maker Lucid has selected ROHM's silicon carbide metal-oxide-semiconductor field effect transistor (SiC MOSFET) for its vehicle Lucid Air. ROHM's SCT3040K and SCT3080K SiC MOSFETs are used in The Wunderbox, the main on-board charging unit in the Lucid Air, integrates a DC-DC converter and the Bi-directional On-Board Charger (OBC), where an advanced power factor correction circuit is capable of operating at high switching frequencies.

The Lucid Air, is a luxury sedan and was named the 2022 MotorTrend Car of the Year. The SiC MOSFET switched OBC can deliver up to 19.2 KW AC charging, adding up to 80 miles of range per hour.

"It was important for Lucid to form strategic alignments with key EV power device suppliers to ensure our future success. ROHM is one of the world's leading suppliers of SiC technology, with strong technical support. We were impressed with ROHM’s strategic investments to increase the production capacity of SiC products, and its development of next generation technologies,” said Eric Bach, Senior Vice President of Product and Chief Engineer, Lucid Group. “Lucid values the close collaborative relationship with ROHM in this work.”

Added Kazuhide Ino, ROHM's Managing Executive Officer, CSO and Director of Accounting & Finance Headquarters: "We are excited to help Lucid develop systems for electric vehicles that maximize the potential of ROHM's SiC MOSFETs. ROHM will continue to strengthen its SiC device lineup, delivering power solutions - such as the charging systems featured in the Lucid Air - that contribute to technological innovation in next-generation automobiles. New products soon to be added, include gate driver Ics that maximize device performance."
