In inductive power transfer (IPT) systems, the same transmitter cannot charge the vehicle at different power levels due to the bifurcation phenomenon. Consequently, IPT chargers with different power ratings are needed, which increases the infrastructural cost. This paper presents a new interoperable single-stage IPT charger for multi-power level wireless charging, comprised of an active clamped AC-AC high-frequency converter and a reconfigurable transmitter-based IPT coupler with switched series-series compensation. The proposed coupler is designed to charge at level-1/level-2 charging with a bifurcation-free phenomenon and its performance is evaluated in the ANSYS-Maxwell platform. The proposed charger is validated through MATLAB simulations, and experimental studies are performed on a 1 kW silicon carbide (SiC)-based FPGA controlled laboratory prototype.
