Apparatus for controlling a plurality of opposing, electrode, direct-currents at pre-set locations across a channel that comprises a converter for converting each electrode current into first and second periodic control signals which are 180°out of phase with respect to each other and which have equal magnitudes corresponding to the magnitude of the associated electrode current; and couplers for magnetically coupling individual ones of the first control signals and for magnetically coupling individual ones of the second signals such that the corresponding electrode currents are equalized or rendered proportional by balancing the same in the same or constant ratios in accordance with the locations of the electrode currents.

Apparatus for controlling electrode current distribution in dc circuits of the type having a plurality of pairs of opposed electrodes along a channel wherein each electrode pair produces a corresponding dc electrode current at a pre-set location across said channel, and the plurality of pairs produces a load current, said control apparatus comprising: means for converting each electrode current into first and second periodic control signals which are 180°out of phase with respect to each other and which have equal magnitudes corresponding to the magnitude of the associated electrode current at preset locations across the channel; and means for magnetically coupling individual ones of said first control signals and for magnetically coupling individual ones of said second control signals such that the corresponding electrode currents are equalized or rendered proportional in the same or constant ratios in accordance with the locations of the electrode currents.
