Abstract
Systems, structures, packages, circuits, and methods provide wireless power and communication signal transmission systems with channel redundancy. Embodiments can be used in mechanical systems having rotating components. Two emission coils can have different topologies and can be used with three or four reception coils. The chosen topologies can be selected to ensure and/or facilitate minimal mutual inductance across topologies when the reception coils are rotated relative to the emission coils. To minimize mutual inductance between coils of different power transmission channels, twists can be added to the coil topologies to alter coil field polarity. Angle sensing can be achieved by determining efficiency of power transmission between the transmission and reception coils.
