Abstract
(DE)
Spannungswandler zur Wandlung einer primärseitigen Wechselspannung auf einem ersten Spannungsniveau in eine sekundärseitige Wechselspannung (auf einem zweiten Spannungsniveau, wobei der Spannungswandler einen Gleichspannungszwischenkreis aufweist, in dem eine aus der primärseitigen Wechselspannung erzeugte erste Gleichspannung mittels eines Gleichspannungs-Gleichspannungs-Wandlers in eine zweite Gleichspannung gewandelt wird, dadurch gekennzeichnet, dass eine Auskopplungsschaltung zur Bereitstellung einer dritten Gleichspannung zum Anschluss wenigstens eines Verbrauchers mit dem Gleichspannungszwischenkreis gekoppelt ist, insbesondere mit dessen Gleichspannungs-Gleichspannungs-Wandler.
(EN)
The invention relates to a voltage transformer for converting a primary-side alternating voltage at a first voltage level into a secondary-side alternating voltage at a second voltage level, the voltage transformer having a DC link in which a first direct voltage generated from the primary-side alternating voltage is converted into a second direct voltage by means of a DC-to-DC voltage converter, characterised in that an output circuit for providing a third direct voltage for the connection of at least one load is coupled to the DC link, in particular to the DC-to-DC voltage converter thereof.
(FR)
L'invention concerne un convertisseur de tension pour convertir une tension alternative côté primaire, présentant un premier niveau de tension, en une tension alternative côté secondaire, présentant un deuxième niveau de tension, le convertisseur de tension présentant un circuit intermédiaire à tension continue, dans lequel une première tension continue produite à partir de la tension alternative côté primaire est convertie au moyen d'un convertisseur continu-continu en une deuxième tension continue. Le convertisseur de tension est caractérisé en ce qu'un circuit d'émission destiné à fournir une troisième tension continue pour l'alimentation d'au moins un consommateur est connecté au circuit intermédiaire à tension continue, en particulier à son convertisseur continu-continu.
