Power Loss Analysis of a Multiport DC – DC Converter for DC Grid Applications [PDF]
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018 In this paper, power losses of a multiport DC – DC converter are analysed. The converter has four bidirectional ports and consists of a triple active bridge and four half bridge converters. As a result, sixteen different operating modes, defined by all combinations of power flow direction, are possible.

Flexible Control of Power Flow in Multiterminal DC Grids Using DC–DC Converter [PDF]
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2016 This paper proposes an efficient control framework that utilizes dc-dc converters to achieve flexible power flow control in multiterminal dc (MTDC) grids. The dc-dc converter employed in this paper is connected in cascade with the dc transmission line, and is therefore named cascaded power flow controller (CPFC).
