This paper proposes a high-efficiency modulation technique for a cascaded H-bridge (CHB) multi-level converter with an integrated battery energy storage system (BESS) for electric vehicles (EVs) ultra-fast charging station. The proposed modulation technique allows improving the conversion efficiency taking advantage of the several redundancies of the power conversion system. In detail, the choice of the output vector is based on the space vector control, whereas its redundancy is selected with the aim to minimize the actual power losses of the converter.

Abstract
This paper proposes a high-efficiency modulation technique for a cascaded H-bridge (CHB) multi-level converter with an integrated battery energy storage system (BESS) for electric vehicles (EVs) ultra-fast charging station. The proposed modulation technique allows improving the conversion efficiency taking advantage of the several redundancies of the power conversion system. In detail, the choice of the output vector is based on the space vector control, whereas its redundancy is selected with the aim to minimize the actual power losses of the converter.File in questo prodotto:
