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.
  • Fig. 1 is a schematic diagram of an embodiment of the inventive arrangement.
  • 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 7 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 I 1 and the current flowing through the current sink C compensation current I c _
  • the load current I 1 by means of a Current / voltage converter W converted into a proportional measurement voltage U 1 .
  • the converter W is, for example, a shunt arranged in the consumer power circuit.
  • the maximum value U lp of the measuring voltage U 1 is determined and in a voltage adder A, the difference between the maximum value U lp and instantaneous value ⁇ 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 for a predetermined load current profile I 1 an optimum with respect to filtering 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 .
  • the peak compensation current I c is set.
  • a corresponding voltage limiter is connected in parallel with the charging capacitor of the peak value rectifier S.

Abstract

L'invention vise à lisser le courant (I) cédé au consommateur (R1) par un récepteur de courant (c) contrôlable et monté en parallèle au consommateur (R1). A cet effet, une tension de mesure (U1) proportionnelle au courant de charge (I1) cédé au consommateur (R1) est dérivée de ce courant de charge (I1). Un dispositif de mesure de valeur de point (S) permet de déterminer sa valeur maximale (U1p). La différence entre la valeur maximale et la tension de mesure (U1p - U1) permet de commander le récepteur de courant (c) asservi en tension de telle façon que la somme du courant de compensation (Ic) s'écoulant par le récepteur de courant (c) et le courant de charge (I1) s'écoulant par le consommateur (R1) soit sensiblement constante.
