摘要： 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.

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.

摘要： A three state class D amplifier (100) comprising a first signal path (1) and a second signal path (1′) substantially identical with the first signal path (1). Each of the signal paths (1, 1′) comprises respective first and second low-pass filter means (10, 10′) coupled to respective input signals (Vn, Vp) provided by input means (Inp, In, Ip), first and second ends (A, B) of a load (5) and to an pulse generator (2) providing a signal having a frequency substantially higher than a frequency of the input signals (Vn, Vp) for generating respective first and second low-pass filtered signals (SUP, SDW). The low-pass filtered signals (SUP, SDW) are inputted to respective comparing means (3, 3′). The comparing means (3, 3′) are coupled to a threshold generator (4) coupled to the input means (Inp, In, Ip) and to first and second reference signals (Vmax, Vmin) representing an estimation of a maximum and a minimum signal value through the load (5) and generating an alternating threshold signal (THRES) that is inverse proportional to a difference between the first and second input signals (Vn, Vp) for maintaining a relative high gain of the amplifier in an idle state.

摘要： A power management integrated circuit comprises a plurality of power source circuits power received at a power supply input terminal to supply power to a plurality of power supply output terminals. A plurality of power source circuits is coupled between the power supply input terminal and the respective power supply output terminals. The power management integrated circuit comprises an active configuration memory and a communication interface with at least one terminal for uploading configuration data from outside the power management integrated circuit into the configuration memory. A control circuit controls operating parameters of respective ones of the power source circuits dependent on the configuration data from the active configuration memory. Thus, the power management integrated circuit is able to switch between different power supply states in a dynamically configurable way, without requiring external control over the configuration during switching.

摘要： 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.

摘要： 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.
