摘要： Adaptation circuits (3) for controlling conversion circuits (1-2) for converting input signals into pulse signals and for converting pulse signals into output signals are provided with generators (30) for generating control signals in dependence of input signals and (basic idea) with compensation circuits (71-72, 81-83) for adjusting the generators (30) in dependence of input information for increasing a stability of output signals, to be able to supply relatively constant output signals to loads (6). The adaptation circuits (3) may reduce dependencies between input signals and output signals and may generate control signals independently from output signals to avoid feedback loops. Input signals may be input voltages, output signals may be output currents, and input information may comprise input voltages and nominal input voltages for compensating for variations of input voltages or may comprise nominal output voltages and input currents proportional to output voltages for compensating for variations of output voltages.

摘要： Operating a lighting device by acquiring a target brightness level of at least one solid-state lighting unit, and determining a reference driving current amplitude for obtaining the target brightness level. If the reference driving current amplitude is below an optimum driving current amplitude, the solid-state lighting unit is operated at the optimum driving current amplitude, which is pulse-width modulated to obtain the target brightness level.

摘要： Recently, the use of class-D audio amplifiers has become more and more widespread. In contrast to the generally employed class-AB linear amplification technology, class-D allows for improved efficiency. However, the class-D principle is known for its poor distortion characteristics. According to the present invention a digital amplifier (18) is provided for converting an audio signal to a power output, comprising a ripple suppression circuit (16) for suppressing voltage ripples in a supply voltage supplied to the bridge circuit with (6) at least one pair of switches. The ripple suppression circuit (16) suppresses ripples in the supply voltage supplied to a switch in the bridge circuit (6), which has been found to cause a major part of the distortions in the output signal of the digital amplifier (18).

摘要： The invention relates an electrical device for providing an output depending on an electrical input. The electrical device (1) is adapted to provide a constant output, if the electrical input is in a first electrical input range, and a dependent output, if the electrical input is in a second electrical input range, wherein the dependent output depends on the electrical input. The output can therefore remain constant, even if the electrical input, which is preferentially a DC grid voltage, fluctuates within the first electrical input range. Moreover, in the second electrical input range the output can be controlled by just controlling the electrical input like the DC grid voltage, without necessarily requiring an additional control construction of the electrical device. A resistance against fluctuations of the electrical input and a controllability of the output can therefore be realized in a relatively simple way.
