A multiport isolated DC-DC converter [PDF]
2016 IEEE Applied Power Electronics Conference and Exposition (APEC), 2016 This paper presents a multi-port isolated DC-DC converter for DC applications. A three-port structure is presented, characterized with full bidirectional power flow and simple control. Galvanic isolation is achieved by means of a multi-winding medium frequency transformer which is a part of a resonant LLC converter.

Hybrid and Modular Multilevel Converter Designs for Isolated HVDC–DC Converters [PDF]
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2018 Efficient medium and high-voltage dc-dc conversion is critical for future dc grids. This paper proposes a hybrid multilevel dc-ac converter structure that is used as the kernel of dc-dc conversion systems. Operation of the proposed dc-ac converter is suited to trapezoidal ac-voltage waveforms.
