Lucid, an advanced luxury electric vehicle company headquartered in California, is using ROHM’s silicon carbide metal-oxide-semiconductor field effect transistor (SiC MOSFET) in the ground-breaking Lucid Air.
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 thanks to the superior performance of the SiC MOSFET. The improved performance at high frequency and high temperature of ROHM’s SCT3040K and SCT3080K SiC MOSFETs have helped Lucid to reduce the size of the design, and to reduce power losses, which results in high charging efficiency.
Lucid’s mission is to inspire the adoption of sustainable energy by creating the most captivating electric vehicles, centered around the human experience. The company’s first car, Lucid Air, is a state-of-the-art luxury sedan with a California-inspired design underpinned by race-proven technology. Customer deliveries of Lucid Air, produced at Lucid’s new factory in Casa Grande, Arizona, are underway.
The Lucid Air was named the 2022 MotorTrend Car of the Year. Additionally, an independent article in InsideEVs confirmed the Lucid Air’s charging capabilities. For example, when connected to DC fast chargers, they found it takes approximately 22 minutes to deliver a charge which will enable select Lucid Air models to cover 300 miles. The SiC MOSFET switched OBC can deliver up to 19.2 KW AC charging, adding up to 80 miles of range per hour.
