Abstract
In the circuit arrangement according to the invention, means (1) 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 (2) which comprises two coupling capacitors (8, 9) and a subsequent full-bridge rectifier (10, 11, 12, 13) at its input, and is coupled at its output to an output capacitance (3) via which the DC output voltage decreases.
