Webinar: Designing silicon carbide solutions for EV fast charging

EV fast chargers bypass the vehicle’s on-board chargers (OBCs) for rapid direct battery charging. This allows batteries to be charged in just 30 minutes versus 4+ hours from OBCs. But the demands of these systems are significant. Design goals for fast chargers call for highly efficient power electronics and very high power density that’s possible… Read more »
