Inductive power transfer (IPT), as a method of wireless power transfer (WPT) via magnetic induction, can be applied to electric vehicles Bosch PIE651BB1E Serie 4 59cm 4 Burners Induction Hob Touch Control Black (EVs) due to its convenience and automation.Interoperability and misalignment tolerance are both major research difficulties for WPT of EVs.This paper proposes a two-channel topology and a coil optimization method, which can improve misalignment tolerance for the unipolar coil (Q) and interoperate with the bipolar coil (DD).Firstly, a topology with phase shift strategy is constructed Padded Overall to increase output ability with Y misalignments and the mathematical model of the proposed topology is established.Secondly, a coil density optimization method is presented to smooth the transmitting mutual inductances fluctuation.

Finally, a 1-kW prototype is built to verify the proposed system which can achieve load-independent constant-current charging.With the Y misalignment of 150 mm, the experimental results agree well with the theoretical analysis.The proposed system is able to interoperate with two types of coils and can achieve misalignment tolerance.
