    摘要: The description concerns a voltage regulator (12) for regulating the output voltage (UB+) of an alternator (10) which is driven by an internal combustion engine. The voltage regulator (12) has an additional circuit (24) which evaluates the exciter current duty cycle (T) and supplies a signal (S1) at its output which is high when the exciter current duty cycle is high and low when the exciter current duty cycle is low. The circuit (24) is integrated in the voltage regulator (12) and the output signal (S1) supplied by it is transmitted via an additional regulator terminal (DA) and can be fed to the control device (25) of the internal combustion engine, where it is used, for instance, to increase the idling speed of the engine and accordingly also to increase the alternator speed and thus the power delivered by the alternator (10). It is also possible to switch off unnecessary consumers with this signal.

    摘要: A generator having an exciting winding and a standard load associated with a standard exciting current in the exciting winding can be controlled by a voltage regulator which adjusts an exciting current in the exciting winding and a temperature measurement device in a predetermined location in the generator and/or a voltage regulator associated with the generator, which is connected to the voltage regulator, advantageously via a microprocessor device or a pulse duration modulation circuit connected to the final regulating stage of the voltage regulator for gating the exciting current. So that the generator can be dimensioned to operate above its maximum rated temperature and can be operated in a superexcited state, the method of controlling the generator includes the steps of increasing the exciting current in the exciting winding beyond the standard exciting current to operate the generator at a higher load than the standard load; measuring a temperature T.sub.G at a predetermined location, advantageously in the generator, with the temperature measurement device; determining an allowed limiting temperature T.sub.GMAX at the predetermined location; lowering the exciting current, I.sub.Err, when the temperature T.sub.G is greater than the allowed limiting temperature T.sub.GMAX and maintaining the output power as high as possible without exceeding the allowed limiting temperature.

    摘要: Fresh air from an area located outside of the engine compartment is supplied to an alternator in a motor vehicle by ventilator. The ventilator is supplied with voltage from the alternator power supply system, and since a failure of the ventilator could lead to destruction of the alternator due to heat, the functioning of the ventilator is monitored by a device or circuit for monitoring and/or controlling the ventilator. This circuit also has a device for self-checking and controls the additional ventilator as a function of the alternator temperature by a device for measuring alternator temperature electrically connected to it.

    摘要: In a device and a method for regulating an alternator increased alternator output is achieved either in that the exciter current can have a value above the nominal exciter current or in that the alternator control parameters are fixed in such a way that overheating could occur under unfavorable circumstances. In order to prevent this overheating even under unfavorable circumstances, the temperature is measured preferably in the regulator and the temperature at critical locations is determined from this temperature while taking into account typical parameters. This can be effected in that the temperature or temperatures which would occur in stationary operation are first determined. When an impermissible temperature is detected, the exciter current is reduced by suitable steps until the allowable maximum temperature is not exceeded.

    摘要: A voltage regulator (4) for a generator (1), particularly for use in motor vehicles, is provided which produces an average field current in the exciting winding (2) of the generator (1) by switching on and off the field current by a controlled semiconductor switch in cooperation with a recovery diode in such a way that the generator voltage remains approximately constant independently of the load and the speed. The voltage regulator (4) contains an integrally acting component for compensating for load-dependent and speed-dependent errors, which component is produced by a nonlinearly working integrator for the relative turn-on period of the current through the exciting winding (2) and is fed back into the regulating circuit of the voltage regulator (4). The nonlinearly of the output variable of the integrator is produced in that, for the formation of the correction function, one period portion during the current flow through the exciting winding (2) of the generator (1) and the controlled semiconductor switch is evaluated differently than the other period portion during the current flow through the exciting winding (2) and the recovery diode.

    摘要: A voltage regulator for generators is proposed which, compared with a voltage regulator known, for example, from DE-PS 27 38 897, is supplemented in such a manner that an integral component corresponding to the relative operating time of the field current is formed and this component is fed into the actual control loop. The relative operating time of the field current in this arrangement can be obtained more or less directly from the switching characteristic of the switching transistor (20) for the field current or by means of a sensing resistor (33) in series with the exciter winding (21).
