    摘要: An inductive power transfer pickup circuit has a pickup coil (L2) and tuning capacitor (C2) connected in series to provide a series resonant circuit. A bi-directional switch (S1) is used to vary the phase angle between the open circuit pickup coil voltage (VOC) and the pickup coil inductor current (iL) to provide a controlled AC supply to an output of the pickup.

    摘要: The present application invention relates to the control of electromagnetic fields. It has particular relevance to magnetic flux coupling apparatus such as inductive power transfer pads for wireless power transfer systems. There is provided a magnetic flux coupling apparatus comprising a coil for generating or receiving magnetic coupling flux and a leakage flux element comprising material of a relatively high magnetic permeability. The leakage flux element is separated from the coil by a region of relatively low magnetic permeability and positioned to provide a controlled path for leakage flux independent of coupling flux. There is provided an electromagnetic wave absorber comprising a high permeability magnetic material arranged in a first layer; and a conductive or low permeability material arranged in a second layer.
