Abstract:
A circuit arrangement for supplying pulse current to one or more electrolytic cells, connected in parallel and having anodes and cathodes, in vertical or horizontal electroplating or etching systems, in which, to supply power to each individual electrolytic cell,a. at least one galvanic rectifier; andb. at least one change-over switch, which can be switched through from at least two inputs to at least one output, or one on/off switch are provided;c. first electric lines for making a direct electrical connection between respectively one terminal of the rectifiers and the one terminal of the electrolytic cell are provided;d. second electric lines for making a direct electrical connection between the respective other outputs of the rectifiers and the inputs of the change-over switches or a terminal of the on/off switch being provided; and in additione. the at least one output of the change-over switches or the other terminal of the on/off switch being directly connected with the other terminal of the electrolytic cell, characterized in that at least one capacitor is connected between said first electric line and each second electric line.
