Power Inter Cell Transformer Modelling for ASV Application

This paper deals with the design of a power intercell transformer (ICT) for a marine drone application. This on-board converter, with a power of the order of kW, is intended to adapt the energy coming from the solar panels to recharge the on-board battery of the vehicle. The constrained application requires special attention to the design of this intercell power transformer. The dimensioning approach by 3D finite element modeling is then essential to apprehend the complexity of the realization of this type of component and to determine the electromagnetic parameters such as the serial resistances of the windings or the proper and mutual inductances of the ICT. The component, thus dimensioned, has been manufactured and the experimental measurements are compared with those from the modeling.
