The SEC-3PH-11-OBC-EVB is a three-phase On Board Charger (OBC) platform achieving state-of-the-art system efficiency with AEC-Q101 SiC power devices and drivers. The system boasts the high performance MOSFET 1200 V, 80 mΩ (NVHL080N120SC1), MOSFET Gate driver 6A (NCV51705) and Diode 650 V, 30 A (FFSB3065B-F085). Conceived in a modular approach and equipped with a user-friendly GUI, the kit facilitates the evaluation of the SiC devices in an OBC application. The LLC system is driven in voltage or current control modes by the embedded software. Ultimately, the platform serves as a learning environment for three-phase AC/DC power conversion.
