Abstract: Techniques are described herein that are capable of increasing efficiency of wireless power transfer. A wireless power transfer system includes features that allow the system to be deployed in public spaces such as airports or in commercial establishments such as restaurants or hotels to allow a user to recharge one or more portable electronic devices while away from home. To accommodate wireless recharging of a variety of device types and states, the system may receive parameters and/or state information associated with a portable electronic device to be recharged and may control the wireless power transfer in accordance with such parameters and/or state information. For instance, the system may increase efficiency of the wireless power transfer based on such parameters and/or state information. The system may also provide a secure and efficient means for obtaining required payment information from the user prior to the wireless power transfer, thereby facilitating fee-based recharging.

Abstract: A semiconductor switch comprises two NMOS transistors coupled in an anti-series arrangement, and a gate control circuit coupled to both gates of the NMOS transistors. Both drains of the NMOS transistors are interconnected, and the gate control circuit is coupled to the drains interconnection. The required chip area is halved compared to prior art switches. Pumping the gates to higher voltages may cause a further reduction of the sizes of the NMOS transistors. In addition advantageously a large range of input and output voltages can be allowed between the sources of the NMOS transistors, whereby the sources act as input and output respectively of the switch, thus allowing application of the switch in a broad technical field.
