Abstract
Systems, methods, and apparatus are disclosed for wirelessly charging an electric vehicle. In one aspect, a method for transferring power via a magnetic field in a wireless power transfer system is provided. The method includes outputting an alternating electric current to a wireless power transmitter, generating, at the wireless power transmitter, the magnetic field in response to being driven with the alternating electrical current, receiving a value indicative of an electrical characteristic of the wireless power transmitter, and adjusting an operating characteristic of the wireless power transmitter to trigger a change in an electrical current in the receiver, the amount of adjustment selected to cause adjustment of an amount of reactive power in the wireless power transfer system based on changes in the receiver that automatically occur to maintain the output power substantially constant in response to the change in the electrical current in the receiver.
