    摘要: The generator regulator includes a transistor power end stage (14) connected to the excitation winding (12) of the generator to provide a pulsed excitation current that passes through the excitation winding during operation and a device for activating and deactivating the transistor power end stage to turn on and off the excitation current in order to provide a predetermined pulse width for the pulsed excitation current passing through the excitation winding so as to maintain a constant output voltage. The device for activating and deactivating the transistor power end stage includes a comparator (16) for comparing a saturation voltage (U.sub.SAT) of the transistor power end stage (14) picked up between the transistor power end stage and the excitation winding with a reference voltage (U.sub.ref) to provide a comparison output and a pulse width modulation circuit (22) for controlling the transistor power end stage (14) to vary the predetermined pulse width of the pulsed excitation current according to the comparison output so that the transistor power end stage (14) is not damaged by short circuits.

    摘要: A voltage regulator for a generator drivable by an internal combustion engine is proposed, in which the triggering of the end stage transistor for varying the exciter current is done with the aid of a pulse width modulator. The digital pulse width modulator employed is a component of a closed-loop control circuit for the exciter current, which uses the generator voltage as the actual value and regulates the pulse width ratio duty factor as a function of the generator voltage detected, and in addition a system damping is performed, in that one entire period of the duty factor can be turned off in overriding fashion. This overridingly turned-off period can be adapted in its duration to the duty factor, thus resulting in a voltage change that is independent of the duty factor. The maximum current rise rate can thus be limited by limiting the maximum rate of change of the pulse width modulator.

    摘要: An electronic circuit device having a monolithic integrated power transistor is disclosed that comprises a parallel connection of a plurality of individual partial transistors (1, 2, 3, . . . , n). In order to stabilize the distribution of the sum current to the individual partial transistors (1, 2, 3, . . . , n) resistors (41, 42, 43, . . . 4n) are provided in their emitter lines. At least one of the resistors (41, 42, 43, . . . 4n) in the emitter lines of the partial transistors (1, 2, 3, . . . , n) serves as measurement resistor for producing a signal voltage proportional to the current to provide an electronic circuit device having current regulation or current limiting, as shown in FIG. 2.

    摘要: In a process and apparatus for monitoring thread breaks without touching the thread, the stochastic electrical charge of the moving thread is detected without contact by means of a metallic plane electrode disposed at the textile machine close to the moving thread. The change of potential upon the occurrence of a thread break is amplified in a high input resistence amplifier. The output of the amplifier is connected to the threshold device directly or by a capacitor. A reference potential is connected to the threshold device input, and the threshold device outputs a binary signal for indicating the condition of the thread.

    摘要: A power transistor monolithic integrated structure produced by a bipolar-epitaxial technology includes a plurality of parallel connected transistor cellular structures each containing at least one component transistor. The base of each component transistor is coupled to a common base control conductor via a protective resistor and a fuse link which melts in the event of a defect in the transistor cell. Another fuse link is incorporated in the branch conductors leading from the collectors of respective component transistor to a common conductor web mounted on the surface of the transistor chip. All transistor cellular structures are electrically isolated one from each other during the manufacturing process.
