Recent Technologies on Integration of Wireless Power Transfer and Photovoltaic Systems

This paper explores the recent technologies applied in the integration of wireless power transfer (WPT) and photovoltaic (PV) systems to provide flexibility, convenience, isolation, safety, etc. A basic introduction to the PV and WPT systems is given. The typical PV systems integrated with WPT are illustrated. PV panels can be integrated in buildings, providing isolation of the building interior and exterior from the unwanted water, air, noise, heat, or light. In electric vehicle (EV) charging systems with PV panels, the connection types, the arrangement of multiple sources, and the control algorithm are shown. Modular designs for low-power applications are also presented. In low-power applications, solar energy can be received wirelessly to power the cooling device in the vehicle cabin without using the vehicle’s power. In some special scenarios, such as lunar rovers and space solar power, WPT and PV are combined to offer advantages over conventional methods. The integration of PV and WPT can enhance the superiority of both sides and extend their boundaries to a new level.
