A compact and integrated wireless charging system is presented in this article for the purpose of charging a photovoltaic (PV) system attached to a building. In such an integrated system, cross-coupling interference presents a challenge, which is addressed by using DD coils and Q coils. Moreover, since cross-coupling has been eliminated, it is convenient and efficient to design corresponding compensation networks. The theoretical analysis shows that the well-designed inductor–capacitor–capacitor-series (LCC-S) compensation structures can provide load-independent constant voltage (CV) output. An experimental setup is successfully built to validate the characteristics of the presented system.
