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.
