ABSTRACT:
The circuit configuration provides an at least approximately load-independent DC voltage. The circuit includes a current control assembly for controlling the mains current consumption, having an AC voltage terminal at which the mains voltage is received and two output terminals. A rectifier assembly is connected to the output terminals of the current control assembly and has output terminals to which the DC voltage is applied. A voltage measurement arrangement, for providing a voltage signal at an output terminal is connected to the output terminals of the rectifier assembly. A feedback branch has a voltage control assembly for feeding the voltage signal back to the current control assembly.
