DE938079C - Current regulator or current equalizer in the form of the Boucherot circuit - Google Patents

Description

In many. Cases, e.g. B. in electrochemical processes such as the formation of electrolytic capacitors or in series connection heated Vers.tärkerrätze, z. B. for the. Distributed along a broadband cable and amplifier tubes heated by it, the same current is required. Included. Should the effort be low and the degree of efficiency high. The well-known Boucharogt circuit proves itself. for this initially useless, since snie is only able to keep a St_ronn equal if the Drossieilspul @ e has no active resistance.

According to the invention works, now the iron choke coil of such a Boucherot circuit in. Saturation area. This increases the internal resistance of the Choke coil = the same, so there was a current balance within very narrow limits Can be reached despite fluctuating mains voltage.

In Fig. Z of the drawing the subject matter of the invention is in one Fig. 2 shows the dependency of the consumer current of the consumer voltage shows. - -The Boucherot circuit is known to exist, as fig. r cedes, lousy. a Reihendrossielspulle z and a parallel to the consumer 2 connected capacitor 3, where DTossdlspule and Korndenr sator together to resonance with the frequency of the voltage U "of the am, the terminals q. and: 5 placed AC network: are coordinated. On the Stromgleiohhalturng the disturbing Ohmsche Wiiders.tand R -the choke coil, drawn in dashed lines. According to the invention This choke coil is designed as a saturation gdr @ os, selspule with a countersink core - and ider SäMigun: gswert z. B. by changing the tap used in the -Drösselspulenwicklung calibrated for equilibrium current.

With subsequent rectification, z. B. for the mentioned, electrochemical Purposes, according to the regulation on constant current also the Sp, annungsgbfaill ides Cdieichri.chters balanced.

From Fig. 2 it can be seen that when the voltage U, the current 1, is changed by changing the load resistance, the current 1 is nevertheless kept the same within very narrow limits (± 3 '/ 0).
