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： 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： 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： Resonant gate driver circuits provide for efficient switching of, for example, a MOSFET. However, often an operation of the resonant gate driver circuit does not allow for an application where high switching frequencies are required. According to the present invention, a pre-charging of the inductor of the resonant gate driver circuit is performed. This allows for a highly efficient and fast operation of the MOSFETs.

摘要： Usually, power supplies are not capable of switching off part of the outputs of a main power supply during stand-by. Due to this, stand-by power supplies are used in addition to operation power supplies. Consistent with an example embodiment, a forward converter is provided, including switches in the rectifier circuit thereof. Due to this, the rectifier circuits may be selectively switched on and off. Advantageously, this may allow that the main outputs of such a forward converter are switched off while on stand-by.
