Abstract

This work introduces a novel battery charger implemented with a four-level three-phase neutral-point-clamped converter and a four-level single-phase dual-active-bridge converter, which offers the intrinsic advantages of multilevel conversion, provides galvanic isolation and allows bidirectional power flow. A detailed and extensive modeling of the system is developed, together with the design of appropriate closed-loop control and modulation. The proposed system allows individual charging of each battery pack, ensuring that the full capacity of the battery bank is utilized, even when the battery packs have different state-of-charge levels, differ in nominal capacities, or use different chemistries. Furthermore, the proposed control system manages the overall DC-link voltage and ensures voltage balance across both DC-links in the system. The effectiveness of the proposed system configuration and control has been validated through simulations. The simulation results show good dynamic response in different operating scenarios, confirming the suitability, feasibility, and benefits of the proposed implementation and control approach.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-04:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 4.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 4 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 1.

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:
