Abstract
In the circuit arrangement according to the invention, means ( ) for generating an alternating voltage from the DC input voltage are provided for gaining an offset-compensated DC output voltage from a DC input voltage, without using transformers and inductances. The alternating voltage is applied to at least one rectifier stage ( ) which comprises two coupling capacitors ( ) and a subsequent full-bridge rectifier ( ) at its input, and is coupled at its output to an output capacitance ( ) via which the DC output voltage decreases.
