Harish Karneddi, Deepak Ronanki, José Rodríguez
Abstract
This letter proposes a new universal integrated onboard charger (IOBC) to achieve a wide output voltage range ranging from 48–450 V for plug-in electric vehicle battery charging applications without employing additional power conversion stages. In addition, a model predictive current control (MPCC) is proposed to accomplish boost and buck operation with inherent seamless mode transitions. The proposed IOBC and the MPCC performance are verified through MATLAB simulations and experimental studies on a dSPACE controller-based laboratory prototype. Finally, the key performance characteristics of the proposed IOBC are comprehensively analyzed and compared with the existing IOBCs.
