Energetic Macroscopic Representation and Inversion-Based Control of a Multi-Level Inverter with Integrated Battery for Electric Vehicles

This paper deals with the Energetic Macroscopic Representation (EMR) of a Multi-Level Inverter with Integrated Battery (MLI-IB) for electric vehicles. The MLI-IB consists of modular cascaded modules connected in series. Each module is composed by an individual battery and an H-bridge converter. An inversion-based control is deduced from the EMR to control the output voltage. In addition, the MLI-IB is managed to balance the state-of-charge of the batteries between the various modules.
