    Abstract: Techniques are described herein that are capable of using an efficiency indicator for increasing efficiency of a 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. The system may provide an efficiency indicator to a portable electronic device that specifies a recommended position of the portable electronic device. The recommended position may correspond to an efficiency with respect to the wireless power transfer that is greater than an efficiency with respect to the wireless power transfer that corresponds to a position of the portable electronic device. The portable electronic device may generate a sensory signal that indicates the recommended position with reference to the position of the portable electronic device.

    Abstract: The present invention relates to a charging circuit and method for generating a charging current supplied to an output terminal (15) to which a battery (40) to be charged is connected. The charging current is indirectly sensed to generate a sensing current having a predetermined relation to the charging current. This sensing current is then compared to a generated predetermined reference current, wherein the charging current is controlled in response to the result of the comparison. Thereby, accuracy, system costs and power efficiency can be increased as a low-ohmic precision resistor is no longer required in the charge current branch of the circuit. Furthermore, the proposed solution enables a simple implementation of the circuit as an integrated circuit.

    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.
