Explanation: I think this should be a "chopper controller", and also should be spelled "Gleichstromsteller" -- at least, the latter spelling yields almost 300 Google hits, all relevant, as against 3 for the spelling without the 's'. The Kluwer Electrotechniek/Elektronica woerdenboek (D/NL/E) gives "chopper" for the version with the s, as do several of the sites that have this term (e.g. www.fh-bielefeld.de/fb2/labor-le/Pdf/le3all.pdf)
