Abstract
Exemplary embodiments of the invention relate to a switched-mode power supply arrangement containing two or more switched-mode power supply transformers (T1 to TN), the primary windings (P1 to PN) of the switched-mode power supply transformers (T1 to TN) being connected electrically in series, an output voltage regulator (AR1 to AR2) being connected to each of the secondary windings (S1 to SN) of the switched-mode power supply transformers (T1 to TN), and the series circuit comprising the primary windings (P1 to PN) being connected to the output of an AC source (WQ). The switched-mode power supply transformers (T1 to TN) can include a ferrite toroidal core (RK1 to RKN), which bears the respective secondary winding (S1 to SN), the series circuit comprising the primary windings (P1 to PN) being in the form of a high voltage-isolated conductor loop (SL) passing through all of the ferrite toroidal cores (RK1 to RKN).
