This paper deals with the design of the magnetic component of an isolated bidirectional multiportconverter. This converter is intended to be embedded in an autonomous surface marine vehicle with a power rating in the kilowatt range and is intended to exchange power between photovoltaic panels, a lithium battery and the propulsion system in which the motors can also be operated as a tidal turbine. This magnetic component is a three-port symmetrical three-phase transformer that allows to interface three three-phase inverters with a six-step control. The converter is galvanically isolated and can operate in a fully bi-directional way. Phase shifting of the inverters allows the power flow between them to be adjusted.
