Aus dieser europäischen Patentschrift ist außerdem bekannt, dass Filterkondensatoren ein Kapazitätsnetzwerk bilden. Weist dieses Kapazitätsnetzwerk drei Kondensatoren auf, so sind diese elektrisch in Stern geschaltet. Weist das Kapazitätsnetzwerk sechs Kondensatoren auf, so sind diese derart angeordnet, dass jeweils drei elektrisch einen Stern bilden, dessen Sternpunkt jeweils mit einem Anschluss des Gleichspan nungs-Zwischenkreises des Spannungszwischenkreis-Umrichters elektrisch leitend verbunden ist.Out this European patent is also known that filter capacitors a capacity network form. Does this capacity network have three capacitors? on, these are electrically connected in star. Indicates the capacity network six capacitors, they are arranged such that in each case three electrically form a star whose star point each with a connection of the dc voltage intermediate circuit of the voltage source inverter is electrically connected.
Ferner ist dieser europäischen Patentschrift zu entnehmen, dass dieses Filter mittels Widerständen bedämpft werden kann. Dazu werden diese Widerstände entweder elektrisch in Reihe zu jeweils einem Filterkondensator oder elektrisch parallel jeweils zu einer Filterdrossel geschaltet.Further it can be seen from this European patent specification that this filter can be damped by means of resistors can. These resistors are either electrically in series with one filter capacitor each or electrically parallel each switched to a filter choke.
Dieses Filter kombiniert ein Gegentakt-Filter mit einem Gleichtakt-Filter. Wenn bei einem Antrieb keine unsymmetrischen Störspannungen auftreten, so genügt die Verwendung eines Gegentakt-Filters. Das heißt, das in der genannten europäischen Patentschrift offenbarte Kombi-Filter für diesen Anwendungsfall überdimensioniert ist.This Filter combines a push-pull filter with a common-mode filter. If there are no unbalanced interference voltages in a drive occur, it is sufficient to use a push-pull filter. The that is, in the said European patent specification revealed combi filter for this application oversized is.

Da der Umrichter neben einer Wirkleistung auch noch induktive Blindleistung bereitstellen muss, fließt aus den Umrichter-Ausgängen ein erhöhter Strom. Das Verhältnis zwischen Wirkleistung und der Wurzel der Summe der Quadrate von Wirkleistung und induktiver Blindleistung wird als Leistungsfaktor bezeichnet. Typischer Wert für einen Leistungsfaktor ist 0,7. Dieses Mehr an Strom fließt nicht nur auf einem Anschlusskabel mit dem ein elektrischer Motor an den Umrichter-Ausgängen angeschlossen ist, sondern auch durch die stromkompensierte Drossel. Dadurch fallen die Wicklungen dieser stromkompensierten dreiphasigen Drossel größer aus und vergrößern das Bauvolumen dieser stromkompensierten Drossel.There In addition to active power, the inverter also has inductive reactive power has to supply, flows out of the inverter outputs an increased current. The ratio between active power and the root of the sum of squares of active power and inductive Reactive power is referred to as a power factor. Typical value for a power factor is 0.7. This extra power not only flows on a connecting cable with the one electrical Motor is connected to the inverter outputs, but also by the current-compensated choke. This will cause the windings to fall this current-compensated three-phase choke larger and increase the volume of this flow-compensated throttle.
Der Erfindung liegt nun die Aufgabe zugrunde, die Größe von stromkompensierten Drosseln bei einem Gleichtakt-Filter eines Spannungszwischenkreis-Umrichters zu reduzieren, ohne dass sich deren Wirkung verändert.The invention is based on the object to reduce the size of current-compensated chokes in a common-mode filter of a voltage source inverter without de changed effect.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 erfindungsgemäß gelöst.These The object is achieved with the features of claim 1 according to the invention.
Dadurch, dass die stromkompensierte Drossel eines dreiphasigen Gegentakt-Filters in einen Gleichspannungs-Zwischenkreis eines Spannungszwischenkreis-Umrichters verlegt ist, wird schon eine Wicklung der dreiphasigen stromkompensierten Drossel eingespart. Außerdem fließt dadurch ein entsprechend einem Leistungsfaktor erhöhter Laststrom nicht mehr durch die stromkompensierte Drossel, wodurch sich das Bauvolumen der verbliebenen zwei Wicklungen dieser stromkompensierten Drossel zusätzlich verringert.Thereby, that the current-compensated choke of a three-phase push-pull filter in a DC link of a voltage source inverter is laid, is already a winding of the three-phase current-compensated choke saved. In addition, it flows accordingly a power factor increased load current through no longer the current-compensated choke, thereby reducing the overall volume of the remaining two windings of this common-mode choke in addition reduced.
Die Erfindung besteht aber nicht allein darin, dass das von den drei Wicklungen der dreiphasigen stromkompensierten Drossel eines Gegentakt-Filters zwei in einem Gleichspannungs-Zwischenkreis eines Spannungszwischenkreis-Umrichters verlegt werden, an dessen Ausgängen dieser Gegentakt-Filter angeschlossen ist, und auf eine dritte Wicklung der stromkompensierten Drossel verzichtet werden kann, sondern auch darin, dass die beiden Sternpunkte des Kapazitätsnetzwerks des Gegentakt-Filters mit einem Anschluss einer Wicklung der stromkompensierten Drossel im Gleichspannungs-Zwischenkreis verknüpft sein muss, der einem netzseitigen Stromrichter des Spannungszwischenkreis-Umrichters zugewandt ist. Das heißt, jeweils an einem gleichspannungsseitigen Anschluss eines netzseitigen Stromrichters eines Spannungszwischenkreis-Umrichters sind jeweils ein Sternpunkt des Kapazitätsnetzwerks des Gegentakt-Filters und eine Wicklung der stromkompensierten Drossel angeschlossen.The But invention is not alone in that of the three Windings of the three-phase current-compensated choke of a push-pull filter two in a DC link of a voltage source inverter be installed, connected to the outputs of this push-pull filter is, and on a third winding of the current-compensated choke can be dispensed with, but also in that the two star points the capacity network of the push-pull filter with a Connection of a winding of the current-compensated choke in the DC link must be linked, the a network-side converter facing the voltage source inverter. This means, each at a DC voltage side connection of a network side Power converters of a voltage source inverter are respectively a star point of the capacity network of the push-pull filter and a winding of the current-compensated choke connected.
Durch diese erfindungsgemäßen Maßnahmen verringert sich die Baugröße der stromkompensierten Drossel eines an den Ausgängen eines Spannungszwischenkreis-Umrichters angeschlossenen Gegentakt-Filters wesentlich.By reduces these measures according to the invention the size of the current-compensated choke one at the outputs of a voltage source inverter connected push-pull filter essential.
