This paper proposes an inductive power transfer (IPT) system with three-bridge switching \ncompensation topology. With the proposed IPT topology, the equivalent circuit and the resonant \ncondition are analyzed to achieve the load-independent constant current (CC) and load-\nindependent constant voltage (CV) outputs. On this basis, multiple power levels can be achieved \nunder CC/CV conditions by bridge arm switching, which makes it possible to complete charging \ntasks for multiple power level electric vehicles (EV) without switching the IPT system. A circuit \nsimulation was built to verify the different power level switching effects of the structure. A 3.3 kW \nIPT system was designed to verify the proposed structure. At the rated output power, the \nexperimental efficiency was up to 92.04% and 91.21% in CC and CV output modes, respectively.
