摘要： Embodiments of the invention pertain to a method and apparatus for planar wireless power transfer where the receiver switches off and/or performs a duty cycle. In an embodiment, the switch can be used in a system that having a high voltage/current solid state switch, without having a high voltage control signal. An embodiment provides a switch that is capable of breaking, or greatly reducing, the connection of the receiver coil and the receiver circuitry in order to enable the receiver to decouple from the power transfer system. This embodiment can allow the transmitter to put out more power to other devices without providing power to the switched device. When the switch is used for a fully charged device, the switching can prevent or reduce damage to the fully charged device.

The push-pull driver circuit is configured to generate a signal. The coil is electrically coupled to the push-pull driver circuit, and the coil is configured to receive the signal from the push-pull driver circuit and wirelessly transmit the signal to a receiver. The sensor is electrically coupled to a virtual alternating current (AC) ground of the push-pull driver circuit or the coil. The sensor is configured to sense a shift in voltage at the virtual AC ground where the shift in voltage is representative of a change of an input impedance of the receiver.
