摘要： An inductive power pad (100) includes a plurality of transmitting inductors (120) and a respective plurality of detector circuits (140). Each transmitting inductor (120) is operable to provide inductive energy to a power receiver circuit (150). Each detector circuit (140) corresponds to one of the plurality of transmitting inductors (120) and each detector circuit (140) is operable to electromagnetically sense a power receiver circuit (150) in proximity thereto. Each detector circuit upon electromagnetically sensing a power receiver circuit, is further operable to control switching of its corresponding transmitting inductor to a power supply (130), thereby providing a supply voltage to said corresponding transmitting inductor, said supply voltage operable to generating inductive energy (110) for transmission to said power receiver circuit.

摘要： The present invention relates to a multiple-output voltage converter. A basic idea of the present invention is to provide a multiple-output converter which may be adapted to various output power conditions. The converter has, in an exemplifying embodiment, three outputs which all share a common tapped inductor (301, 302). An inductor tap is employed to control the inductance of the inductor. A large inductance is used for low power standby operation and a small inductance is used when, for example, the LED backlight is switched on. Switches are arranged at the converter outputs to select to which one of the respective converter outputs the energy of the inductor is to be transferred.

摘要： Organic light emitting diode arrangement Organic light emitting diode arrangements (1) are, to protect them against an effect of a switch-on, provided with circuits (31-36) for, during a first time interval that follows a switch-on, limiting a current through the organic light emitting diode arrangement (1) more and for, during a second time interval that follows the first time interval, limiting the current less. The circuit (31-36) may be passive such as a negative temperature coefficient resistor (31) or a series inductor (32) possibly with a freewheel diode (40) or may be active such as a switchable resistor (33) that is not bridged during the first time interval and that is bridged during the second time interval or a switchable resistor that is bridged in response to a detection of a value of the current exceeding a threshold value or such as a part of a converter (63) that is controlled in response to a detection of a value of the current.
