This paper proposes a novel LCC-SP compensation topology for inductive power transfer (IPT) system and its tuning methods to enhance misalignment tolerance. The impedance condition and the constant current output characteristic of the newly proposed topology are analyzed, followed by a detailed derivation of compensation parameters based on the discussion about resonant tank. The realization of zero voltage switching (ZVS) and reactive power demand are discussed by theoretical deduction and numerical simulation. Then, the parameters detuning method to enhance misalignment tolerance is presented and it is found that a stable output current is maintained over a wide misalignment. Compared to traditional compensation topologies, the newly proposed compensation topology provides the advantages of easy achievement of ZVS, high design freedom and high misalignment tolerance. Finally, the IPT prototype with the LCC-SP compensation network is built and tested. The experimental results match well with the calculations, validating the correctness of theoretical analysis. |
