  • Patent number: 4595846
    Abstract: A first circuit branch subjected to an input voltage and including a first resistance and a second circuit branch subjected to a reference voltage and including a second resistance are connected to a coupling circuit, which is responsive to the current circulating in the first branch to cause a current of the same value to circulate in the second branch. An output voltage taken at a point between said coupling circuit and said second resistance constitutes the modified signal.

  • Patent number: 4455585
    Abstract: An electric power generator which includes a component, for example, a Zener diode, connected in series with the usual return diode which is connected in parallel to the excitation winding of the alternator. The Zener diode makes it possible to set the discharging voltage due to the energy stored in the magnetic field associated with the inductance of the excitation winding at a relatively high level during high-voltage transients caused by the accidental disconnection of the wire connecting the alternator to a load or a terminal of the motor vehicle battery while it is in the charging stage. The result is a more rapid dissipation of the energy stored in the excitation circuit, and therefore results in an output transient having a reduced energy content. Thus, it is possible to construct a voltage regulator and such other devices as may be powered by the alternator in the form of low-voltage integrated circuits.
