Abstract (en)
[origin: EP0886200A2] The circuit arrangement includes a first rectifier arrangement (GL1) with an AC voltage connection (EK1, EK2) and two output terminals (AK1, AK2), and a current regulator arrangement (SRA) connected to the output terminals of the first rectifier arrangement. A second rectifier arrangement is connected to two output terminals (AK3, AK4) of the current regulator arrangement, which provides an output voltage (Ua) at two output terminals (AK5, AK6). A voltage measurement arrangement (MA) is connected to the output terminals of the second rectifier arrangement to provide a voltage signal (SS) at its output. A feedback branch includes a regulator arrangement (RA) with an integrator arrangement (IN) for feeding the voltage signal to an input terminal (EK) of the current regulation arrangement. A function generator is arranged in the feedback branch in connection to the regulator arrangement. The function generator provides an output signal (y) from an input signal (x), according to a predetermined function (y=f (x) ), whereby the functions increases at least partially with increasing input signal.
