Abstract
A current control system comprising at least one series arm including a linear series regulator for generating a manipulated variable signal, wherein the linear series regulator is connected to a semiconductor control element which is connected to a supply voltage referenced to a ground potential, and the semiconductor control element includes an output voltage at its output side relative to the ground potential. A reference signal fed to the series regulator, a current measurement signal, and the manipulated variable signal are referenced to the ground potential, where the manipulated variable signal is fed to a subtractor which subtracts the difference of the feed voltage minus the output voltage from the manipulated variable signal, and the generated output signal of the subtractor is fed to the semiconductor control element as a corrected manipulated variable signal.
