Definitions

  • the invention relates to an arrangement according to the preamble of the main claim.
  • the compensation current generated by the current sink is not obtained by regulation but by control.
  • Such an arrangement is therefore very fast and stable and adapts independently also relatively fast load current changes.
  • the invention shows an arrangement according to the invention for smoothing the consumer direct current I supplied to a consumer R 1 by means of a controllable current sink C connected in parallel to the consumer R 1 .
  • This voltage-controlled current sink C is in principle a controlled consumer. It is realized in modern circuit technology preferably by controllable transistors combined with corresponding resistors.
  • the total consumer current I which is supplied from a DC source, not shown, the load R 1 , is composed of the sum of the load R 1 supplied to the load current I 1 and the current flowing through the current sink C compensation current I c .
  • the load current I 1 is converted by means of a current / voltage converter W into a proportional measuring voltage U 1 .
  • the converter W is, for example, a shunt arranged in the load circuit.
  • the maximum value U 1p of the measuring voltage U 1 is determined, and in a voltage adder A the difference between the maximum value U 1p and the instantaneous value U 1 is determined.
  • the filter effect of the arrangement according to the invention is determined by the accuracy of the measurement of the load current I 1 as well the control accuracy of the current sink C determined.
  • the response and discharge time of the peak value rectifier S and the average value of the obtained through this peak value rectifier maximum value of the measuring voltage and the derivative of the instantaneous value U 1 of proportional to the load current measuring voltage are dimensioned such that an optimum with respect to a predetermined load current profile I 1 filter effect and power loss in the current sink C results.
  • the current compensation circuit is also associated with a non-illustrated switching device through which the compensation current I c is switched on and off together with the consumer R 1 . Furthermore, by limiting the maximum value U 1p ascertained in the peak value rectifier S, the peak compensation current I c is set. For this purpose, for example, a corresponding voltage limiter is connected in parallel with the charging capacitor of the peak value rectifier S.

Claims (3)

  1. Dispositif pour lisser le courant (I) délivré à un consommateur (R1) avec un réservoir de courant contrôlable (C) connecté en parallèle avec le consommateur (R1) et un dispositif de mesure de valeur de crête (S), ce dispositif étant adapté de telle manière que
    à partir du courant de charge (I1) délivré au consommateur (R1) soit dérivée une tension de mesure (U1) proportionnelle à celui-ci, dont la valeur maximale (U1p) est déterminée au moyen du dispositif de mesure de valeur de crête (S),
    le réservoir de courant commandé en tension (C) soit commandé avec la différence entre la valeur maximale et la tension de mesure (U1p - U1) de manière que la somme du courant de compensation (Uc) circulant à travers le réservoir de courant (C) et du courant de charge (I1) délivré au consommateur (R1) soit sensiblement constante,
    la valeur maximale (U1p) de la tension de mesure (U1) soit limitée à une valeur prédéterminée par le biais d'un limiteur de tension,
    la valeur moyenne du courant de compensation (Ic) du réservoir de courant (C) et la température du réservoir de courant (C) soient déterminées et la limitation de la valeur maximale (U1p) soit déterminée en fonction de celles-ci de manière que, dans le cas d'une surcharge, l'effet de filtrage soit limité et affaibli en conséquence.
  2. Dispositif selon la revendication 1,
    adapté de telle manière que
    la tension de mesure (U1) proportionnelle au courant de charge (I1) sur une résistance de dérivation située dans le circuit et la valeur maximale de cette tension de mesure soit mesurée au moyen d'un redresseur de valeur de crête (S).
  3. Dispositif selon l'une des revendications précédentes,
    adapté de telle manière que
    le dispositif puisse être activé et désactivé conjointement au consommateur (R1) par le biais d'un dispositif de commutation.
