This work proposes an architecture that integrates renewable energy sources or photovoltaic (PV) systems with the dc link of utility and acts as primary and secondary energy sources to the electric vehicle (EV) load. The proposed architecture contains the dc link cascaded single-stage conventional H-bridge, which superimposes a dual boost interleaved (DBI) topology with a series–series resonant (SSR) converter system. Furthermore, the SSR side contains a wireless charging system followed by the diode bridge rectifier and a Li-ion battery as an EV load. It is challenging to integrate the above system with reduced power stages. Moreover, achieving power control in an integrated single-stage system makes it more complex. Therefore, this work includes a fundamental operation and analysis of the proposed architecture. A system-level power management scheme is also provided to control the proposed system. This power management scheme includes four basic power modes that comply with different system conditions during its operation. Furthermore, the essential of the power management scheme is to ensure that the utility should support the charging structure during excess or shortage of power flow between PV and EV load. Finally, the proposed architecture has been validated using MATLAB simulation and a 1.2-kW hardware prototype.
