Abstract
Exemplary embodiments of the invention relate to a switched-mode power supply arrangement containing two or more switched-mode power supply transformers (Tto TN), the primary windings (Pto PN) of the switched-mode power supply transformers (Tto TN) being connected electrically in series, an output voltage regulator (ARto AR) being connected to each of the secondary windings (Sto SN) of the switched-mode power supply transformers (Tto TN), and the series circuit comprising the primary windings (Pto PN) being connected to the output of an AC source (WQ). The switched-mode power supply transformers (Tto TN) can include a ferrite toroidal core (RKto RKN), which bears the respective secondary winding (Sto SN), the series circuit comprising the primary windings (Pto PN) being in the form of a high voltage-isolated conductor loop (SL) passing through all of the ferrite toroidal cores (RKto RKN).
