Control of a Modular DC-DC Converter Dedicated to Energy Storage

A DC-DC converter system is presented based on an Input-Series/Output-Parallel Dual Active Bridge structure, in a full modular design. The association of 4 elementary modules leads to a one stage DAB. The proposed converter is dedicated to interface a DC-voltage network with a battery based energy storage device. The paper aims to define and test a suited control strategy able to equalize the power flow in the two channels. The control is established using the Energetic Macroscopic Representation and the associated Inversion Based Control. The modelling method for elaborating the control is presented, together with experimental results.
