Abstract:To improve the interoperability and misalignment tolerance of the inductive power transfer (IPT) system, the concepts of circular rotating magnetic field control and elliptical rotating field orientated control(FOC) are proposed in this paper. The method of analogy analysis between LIM (liner inductive motor) and IPT is adopted to improve the magnetic field distribution characteristics. Detailed output voltage derivation of circular pads and DD pads under misalignment are given. An approximate calculation model is built to study the influence of end effect and gap variation on magnetic field distribution. Experimental results verify the laws of circular magnetic field and elliptical magnetic field.
