A Reconstructed S-LCC Topology With Dual-Type Outputs for Inductive Power Transfer Systems.

In inductive power transfer (IPT) applications, load-independent output has become more popular. This letter proposes a reconstructed S-LCC topology with dual-type outputs, which can realize constant current (CC) output and constant voltage (CV) output simultaneously. The proposed reconstructed S-LCC topology uses the same number of passive components, inductor or capacitor, as conventional S-LCC topology while provides dual-type outputs, which results in reduced cost and size. Such dual-type outputs could be treated as two independent output ports without using any decoupling methods, which can simplify the parameter design significantly. The circuit model of the proposed reconstructed S-LCC topology is analyzed in detail. Comparison between the proposed reconstructed S-LCC topology and multicoil structure is performed. Experimental prototypes with 300V/1.5 kW CV output and 10A/1 kW CC output are fabricated to verify the feasibility of the proposed topology. [ABSTRACT FROM AUTHOR]
