In this contribution, the authors evaluate the possibility of using separated access points for power and data transfer in a coupled Wireless Power Transfer-Powerline Communication system. Such a system has been previously proposed by the authors for specific applications, in which Wireless Power Transfer (WPT) should take place in a system where data are transmitted over the power grid. In previous works the authors have performed lab tests on a two coils WPT system equipped with a set of filters to also allow an efficient data transfer. When a multiple coil WPT system is chosen, additional possibilities arise: the access point for power and data can be differentiated, with the aim of maintaining the designed power efficiency and increase data transfer capacity. In this study a four coils WPT system is thoroughly analyzed, modelled, implemented and measured, and a set of guidelines for the correct design (in terms of performance optimization) of the data transfer is given.
