Abstract
(DE)
Eine Ladeschaltung (LS) für einen fahrzeugseitigen elektrischen Energiespeicher (ES) weist auf: einen Wechselstromanschluss (WA), mindestens zwei Glättungskondensatoren (C1, C2), eine Konfigurationsvorrichtung (KV) und einen Gleichrichter (GR). Über den Gleichrichter ist der Wechselstromanschluss (WA) mit der Konfigurationsvorrichtung (KV) verbunden. Die Konfigurationsvorrichtung (KV) verbindet den Gleichrichter (GR) mit den Glättungskondensatoren (C1, C2) Die Konfigurationsvorrichtung (KV) ist eingerichtet, die Glättungskondensatoren (C1, C2) wahlweise in paralleler oder serieller Konfiguration miteinander zu verbinden. Der Wechselstromanschluss weist einen Neutralleiteranschluss (N) auf, der über eine Diodenschaltung (DE) mit der Konfigurationsvorrichtung (KV) verbunden ist. Die Konfigurationsvorrichtung (KV) weist mindestens einen ersten Schalter (S1, S3) auf, der derart in der Konfigurationsvorrichtung (KV) vorgesehen ist, dass dieser in geschlossenem Zustand die Glättungskondensatoren (C1, C2) parallel miteinander verbindet. Die Konfigurationsvorrichtung (KV) weist eine Diode (DS) auf, die derart in der Konfigurationsvorrichtung (KV) vorgesehen sind, dass diese in geschlossenem Zustand die Glättungskondensatoren (C1, C2) seriell miteinander verbindet.
(EN)
The invention relates to a charging circuit (LS) for a vehicle-side electrical energy store (ES), having: an alternating current connection (WA), at least two smoothing capacitors (C1, C2), a configuration apparatus (KV) and a rectifier (GR). The alternating current connection (WA) is connected to the configuration apparatus (KV) via the rectifier. The configuration apparatus (KV) connects the rectifier (GR) to the smoothing capacitors (C1, C2). The configuration apparatus (KV) is designed to connect the smoothing capacitors (C1, C2) to each other either in parallel or serial configuration. The alternating current connection has a neutral conductor connection (N), which is connected to the configuration apparatus (KV) via a diode circuit (DE). The configuration apparatus (KV) has at least one first switch (S1, S3), which is provided in the configuration apparatus (KV) such that, in the closed state, the first switch connects the smoothing capacitors (C1, C2) to each other in parallel. The configuration apparatus (KV) has a diode (DS), which is provided in the configuration apparatus (KV) such that the diode connects the smoothing capacitors (C1, C2) to each other serially when in the closed state.
(FR)
L’invention concerne un circuit de charge (LS) destiné à un accumulateur d’énergie électrique (ES) embarqué dans un véhicule, comprenant : une borne de courant alternatif (WA), au moins deux condensateurs de lissage (C1, C2), un dispositif de configuration (KV) et un redresseur (GR). Le redresseur permet de relier la borne de courant alternatif (WA) au dispositif de configuration (KV). Le dispositif de configuration (KV) permet de relier le redresseur (GR) aux condensateurs de lissage (C1, C2). Le dispositif de configuration (KV) est conçu pour relier les condensateurs de lissage (C1, C2) dans une configuration sélectivement de montage en parallèle ou de montage en série. La borne de courant alternatif présente une borne neutre (N) qui est reliée au dispositif de configuration (KV) par l’intermédiaire d’un circuit à diodes (DE). Le dispositif de configuration (KV) présente au moins un premier commutateur (S1, S3) qui est prévu dans le dispositif de configuration (KV) de manière à relier, en mode fermé, les condensateurs de lissage (C1, C2) ensemble en montage parallèle. Le dispositif de configuration (KV) présente une diode (DS) qui est prévue dans le dispositif de configuration (KV) de manière à, en mode fermé, relier ensemble les condensateurs de lissage (C1, C2) en montage en série.
