Stromrichterschaltungsanordnung vorzugsweise für Energieaufbereitung in Photovoltaik-Systemen oder Systeme mit Gleichstrom-SpeichernPower converter circuit arrangement preferably for energy processing in photovoltaic systems or systems with direct current storage

Liegt die Ausgangsspannung eines Photovoltaik-Generatorsystems zur Versorgung verschiedener Wechselstrom-Verbraucher unterhalb der geforderten Nenngröße einer Wechselspannung, so muß die Energieaufbereitungseinheit die Generatorspannung auf das erforderliche Niveau hochsetzen und wechselrichten.If the output voltage of a photovoltaic generator system for supplying various AC consumers is below the required nominal value of an AC voltage, the energy processing unit must increase the generator voltage to the required level and convert it into an inverter.

Die zur Zeit dafür verwendeten Wechselrichter bestehen daher aus einer hochsetzenden Einheit (Hochsetzsteller, potentialgetrennte DC-Wandler oder 50 Hz-Transformator) und einer wechselrichtenden Einheit (Pulswechselrichter oder 50 Hz-Brücke). Die beiden Einheiten werden als Kettenschaltung verbunden. Bei der Systemvariante "hochsetzende Einheit (DC-Wandler) mit nachgeschalteter wechselrichtender Einheit" wirkt sich die Kettenschaltung zweier Stromrichter negativ auf den Wirkungsgrad aus. In der Variante "wechselrichtende Einheit mit nachgeschalteter hochsetzenden Einheit (50 Hz-Transformator)" fällt der schwere und große Transformator zusätzlich als Nachteil ins Gewicht.The inverters currently used for this purpose therefore consist of a step-up unit (boost converter, isolated DC converter or 50 Hz transformer) and an inverter unit (pulse inverter or 50 Hz bridge). The two units are connected as a chain connection. In the system variant "step-up unit (DC converter) with downstream inverter unit", the chain connection of two converters has a negative effect on the efficiency. In the variant "inverter unit with downstream step-up unit (50 Hz transformer)", the heavy and large transformer is an additional disadvantage.

Erfindung:Invention:

Vorteilhafte Wirkung:Beneficial effect:

Die Verwendung einer Vollbrücke in einer Kettenschaltung mit einer hochsetzenden Einheit ist deshalb notwendig, weil die wechselrichtende Einheit tiefsetzende Eigenschaften hat.The use of a full bridge in a ladder circuit with a step-up unit is necessary because the inverter unit has step-down properties.

Die Anwendung der im Anspruch 1 und in den Unteransprüchen formulierten Anordnung und Maßnahmen ermöglicht die Vereinigung der beiden Funktionen des Hochsetzens und des Wechselrichtens unter in Anspruchnahme nur einer einzelnen Einheit.The application of the arrangement and measures formulated in claim 1 and in the subclaims enables the combination of the two functions of boosting and inverting using only a single unit.

Mittels den in den Ansprüchen 1 bis 3 formulierten Anordnungen und Maßnahmen kann die niedrige Generatorspannung gleichzeitig auf das gewünschte Niveau hochgesetzt und wechselgerichtet werden, ohne daß eine Kettenschaltung aus zwei Funktionseinheiten mit den oben genannten Nachteilen notwendig ist.By means of the arrangements and measures formulated in claims 1 to 3, the low generator voltage can be increased to the desired level and reversed simultaneously, without the need for a chain connection of two functional units with the disadvantages mentioned above.
