System and method for inductive charging of portable devices
Afshin Partovi,Michael Sears +1 more
TL;DR: In this paper, the authors present a system and method for variable power transfer in an inductive charging or power system. In accordance with an embodiment, the system comprises a pad or similar base unit that contains a primary, which creates an alternating magnetic field, and a receiver comprises a means for receiving the energy from the magnetic field from the pad and transferring it to a mobile device, battery, or other device.
Patent
Contact-less power transfer
TL;DR: In this paper, a system and method for transferring power without requiring direct electrical conductive contacts is described, where a primary unit having a power supply and a substantially laminar charging surface having at least one conductor that generates an electromagnetic field when a current flows there through and having an charging area defined within a perimeter of the surface, the at least conductor being arranged such that electromagnetic field lines generated by the at most one conductor are substantially parallel to the plane of the ground surface or at least subtend an angle of 45° or less to the surface within the charging area.
