Abstract

A description is given of a circuit arrangement for converting an input AC voltage into a rectified output voltage with a rectifier circuit (G) and a charging capacitor (CHV) downstream in the circuit arrangement. The circuit arrangement additionally includes a stabilizing capacitor (C1, C2) which is connected in parallel to the charging capacitor (CHV) so that the stabilizing capacitor (C1, C2) is charged to its maximum when the charging capacitor (CHV) is charged, until the value of the voltage present on the stabilizing capacitor (C1, C2) corresponds to a fraction of a maximum peak voltage present on the charging capacitor (CHV). This stabilizing capacitor is discharged, in essence, only when the voltage present on the charging capacitor (CHV) drops below the value of the voltage present on the stabilizing capacitor (C1, C2).
