Abstract
Systems and methods of wireless power transfer system with interference detection disclosed herein detects possible excessive energy transfer associated with parasitic metal objects placed in close proximity with system coils by comparing power received on the receiving side of the system with the power consumed on the primary side considering known losses in the system. If the result of such comparison shows that power consumed on the primary side substantially exceeds power received on the secondary side, the system may terminate operation.
