摘要： The invention relates to a standby circuit, an electrical device with a standby circuit, a method for the control of the electrical device and a power supply assembly. Whereas the power supply unit and the control electronics are in permanent operation when conventional devices are in the standby mode and consequently have a high power consumption, the invention proposes a solution for saving energy while retaining convenience of operation by which the power supply unit is switched off in the standby mode. A standby circuit, preferably fed by an energy buffer element, remains active in the standby mode and monitors signal inputs for activation events. When an activation event occurs, the standby circuit switches on the power supply unit.

摘要： The present invention relates to a lighting device, as well as to a lighting system comprising such a lighting device and an adjustable power source, and also relates to a method of driving such a lighting system. The lighting device comprises at least one LED (1a, 1b), a control device that comprises a measuring means (7, 9) to measure a quantity that is indicative of an electrical resistance of said LED at a predetermined current or voltage, a power supply control means (11) connected to said measuring means (7, 9) and constructed to control an adjustable electrical power supply (3a, 3b) for driving the LED (1a, 1b), said signal being based on said value of said quantity. The electrical resistance of a LED is functionally dependent of the LED's junction temperature, which in turn determines its optical output characteristics. Thus, by measuring the junction temperature indirectly, through measuring of electrical LED characteristics, and mapping them to a temperature, LED output control is possible.

摘要： The invention relates to a DC/DC converter for use in a decentralized power generation system. If a DC/DC converter is physically separated from a power receiving component and connected to such a power receiving component via a DC bus, a short-circuit on the DC bus may endanger the system and service personnel. In order to minimize such a risk, it is proposed that the DC/DC converter comprises a converting component for DC/DC converting a direct current supplied by a power generating unit and for supplying a resulting converted direct current to a DC bus, and that the DC/DC converter comprises in addition a control component arranged to monitor a voltage at the outputs of the DC/DC converter and to cause the converting component to enter a short-circuit protection mode if the monitored voltage lies below a predetermined voltage threshold. The invention relates equally to a corresponding system and to a corresponding method.

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 die bridge circuit with (6) at least one pair of switches. The ripple suppression circuit (16) suppresses ripples in die 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： A circuit arrangement is described for a microcontroller having an improved energy consumption which is achieved in that the microcontroller (2) is connected to its operating clock only during evaluation of a signal. A switching means (5) through-connecting the operating clock when a “logic 1”, signal is present at the control input is arranged between the microcontroller (2) and the clock generator (6). This “logic 1” signal is generated by setting a flip-flop (4, 7) for example, when receiving a remote control signal. The program run of the microcontroller (2) is stopped at a defined breakpoint so that there is no transient time.

摘要： The present invention relates to a bidirectional semiconductor switch (M1, M2) with extremely low control power consumption and a bootstrap circuit which allows reliable start of operation of the switch and the hosting device after unlimited duration of mains interruptions. Intelligent control options are provided by operating from a small energy storage and no extra means are required to recover from a depleted energy storage condition. The absence of audible noise and mechanical wear also enables more frequent recharging cycles and allows smaller and thus cheaper energy storage components.
