摘要： A receiver unit of a wireless power transfer system is presented. The receiver unit includes a main receiver coil, a plurality of auxiliary receiver coils disposed about a central axis of the main receiver coil, and a receiver drive subunit. The receiver drive subunit includes a main converter operatively coupled to the main receiver coil and having a main output terminal. The receiver drive subunit may include a plurality of auxiliary converters operatively coupled to the plurality of auxiliary receiver coils. The plurality of auxiliary converters may be operatively coupled to each other to form an auxiliary output terminal coupled in series to the main output terminal to form a common output terminal. In some implementations, the receiver drive unit may be formed on a substrate of an integrated electronic component. The integrated electronic component may further include a communication subunit and a controller disposed.

摘要： A method includes utilizing a detection device comprising a detection mat having a plurality of detection coils, and at least one pair of groups of detection coils having a first group of detection coils and a second group of detection coils, and where the first group of detection coils includes a first impedance value, and a second group of detection coils includes a second impedance value. The method further includes determining alignment parameters representative of electromagnetic coupling between at least one pair of groups of detection coils of the detection mat and an electromagnetic field generated by an apparatus coil, and comparing the alignment parameters with a reference. The method also includes generating a control signal indicative of an alignment position of the apparatus coil with respect to the detection mat based on the compared alignment parameters.
