    摘要: A control circuit for a direct-current motor driven in a clocked manner, includes an electrolytic capacitor connected in parallel and free-wheeling diode. Spurious radiation is reduced, in that a choke is connected between the positive motor supply voltage and the plus terminal of the electrolytic capacitor, and that the free-wheeling diode is disposed with its cathode between the choke and the electrolytic capacitor, and with its anode on the negative side of the d.c. motor.

    摘要: A device for operating a gas discharge lamp has a d.c.-d.c. converter which converts an input voltage based on a reference potential into two output potentials different from the reference potential. The gas discharge lamp is brought by a drive circuit to these output potentials having different absolute values.

    摘要: A clocked power supply circuit having an at least intermittently active load that is independent of a consumer, in particular for supplying power to gas-discharge lamps as consumers, contains a dc/dc converter comprising a transformer. Switching elements connect the converter to a dc voltage source in the timing of a control arrangement which makes available switching signals for the switching elements as a function of the prevailing output-side load state. The transformer of the dc/dc converter is designed so that two voltages (U+, U-) of differing polarity and magnitude, are able to be tapped off from the output side. At least one of these voltages is regulated and provided for supplying power during operation of the consumer. The at least intermittently active load can be switched to the regulated voltage.

    摘要: A power-supply circuit having a switching regulator (10) and at least one additional circuit (14, 14') whose two respective outputs (11, 17) are guided together to a common or joint output (18) by diodes (D3, D3'; D4). The additional circuit (14, 14') produces, from an alternating quantity (15) occurring inside the switching regulator (10), a second output voltage (U+, U'+) that is in a second output-voltage range and is more positive with respect to the first output voltage (U-) that is made available at the first output (11) of the switching regulator (10) and is in a first output-voltage range. A gas-discharge lamp, for example, is provided as the load (L) between the first and second outputs. The division of the voltage ranges to be made available for the load (L) into at least two partial ranges permits a high effectiveness of the current-supply circuit of the invention.

    摘要: A headlamp for a power vehicle comprises a reflector having an apex, a light source arranged in the apex of the reflector, and a dimming device which is formed so that in a position for high beam it allows light from the light source to reach a lower reflector region or allows the light to exit the same, and in a position for low beam it keeps away light from said light source from the lower reflector region or blocks light reflected from the lower reflector region. The light source is formed as a gas discharge lamp with an axial light arc, an upper reflector region is formed for producing a light distribution for low beam while the lower reflector region is formed for producing a light distribution for high beam.

    摘要: A method is proposed for monitoring a computer network having at least two subscribers connected via a databus comprising at least two lines, said subscribers having in each case one receiving component and/or one transmitting component. The method is characterized by the fact that the functioning of the databus and/or the functioning of the subscriber is monitored with the aid of error detection signals (watch-dog signals, CEI) of at least one subscriber, and emergency operation measures (M1; M2), matched to the respective error case, for setting defined emergency modes of operation (single-wire mode, special emergency mode) are taken. After taking the first emergency operation measure (M1), it is tested whether the computer network is functioning free of errors. If this is the case, the first emergency operation measure is maintained and thus also the emergency mode of operation (single-wire emergency mode) adopted. If further errors should arise in the computer network after the first emergency operation measure has been taken, the first emergency operation measure is cancelled and the second emergency operation measure (M2) is taken. If, from now on, no further errors arise, the emergency operation mode, the special emergency mode, set by this measure is maintained. Only if further errors continue to arise are the affected subscribers or the entire computer network switched off (bus-off).

    摘要: A method is proposed for influencing the electrical power of a load with the assistance of a pulse-width modulated signal, the latter including the requirement of a continuous turn-on signal. The method provides that the continuous turn-on signal is terminated by an interrupt signal and that the continuous turn-on signal is followed by a clock-pulse phase having at least one fundamental period duration of the pulse-width modulated signal, the period including a turn-off time. The occasional interruption of the pulse-width modulated signal, which is present as the continuous turn-on signal, makes it possible to detect an operational quantity of the load that only arises during a power change in the load.

    摘要: An arrangement for detecting the condition of a high pressure gas discharge lamp when switched on is described, where a control unit either injects a defined current into the lamp and measures the resulting voltage drop, or it applies a defined voltage to the lamp and measures the lamp current flowing in so doing and, depending on the result, it starts the lamp according to the condition of the lamp thus determined.
