This project focuses on the design and evaluation of an affordable bidirectional onboard charger (OBC) for electric vehicles as part of the 2026 International Future Energy Challenge (IFEC). The system is designed to convert AC grid power to a regulated DC output, while also enabling bidirectional power flow for vehicle-to-grid and energy storage applications. The system includes a two-stage electromagnetic interference (EMI) filter, a totem-pole bridgeless power factor correction (PFC) stage for AC–DC conversion, and a full-bridge dual active bridge (FBDAB) converter for isolated DC–DC power transfer. The TTPL PFC stage is used to achieve high efficiency and near-unity power factor while reducing conduction losses. The isolated DC–DC stage uses phase-shift modulation to enable bidirectional power flow and soft-switching operation. Control of both power stages is implemented using the Texas Instruments TMS320F280049C microcontroller, which provides high-resolution PWM generation, integrated ADCs, and fast control capabilities. The design also includes EMI filtering, sensing circuits, magnetic component selection, and thermal management considerations to meet IFEC goals for efficiency, power density, and affordability.
