                    On November 6th, the second day of CIIE, a large number of GaN and SiC products became the focus of the audience.

                     


                    Automotive electronics is a key service area of Nexperia. Each new car uses about 270 Nexperia products in different application areas, such as automotive and electric vehicle powertrains, automotive DC motor controls and on-board chargers. In the face of the rapid development of domestic electric vehicle market, as a reliable supplier of high-efficiency gallium nitride (GaN) and silicon carbide (SiC), Nexperia exhibited a large number of gallium nitride and silicon carbide products during the 4th China International Import Expo. Including new energy vehicle motor controller using 35 kW Gallium nitride (GaN) power module, 50 kW power system inverter, 3 kW gallium nitride (GaN) DCDC car charger, 4 kW gallium nitride (GaN) bridgeless totem pole PFC, the first industrial grade 650V/10A silicon carbide (SiC) Schottky diode.

                     

                    The new energy vehicle motor controller with 35 kW Gallium nitride (GaN) power module is jointly developed by Shanghai Automotive Electric Drive Co., LTD and Nexperia Semiconductor (China) Co., LTD.
