Description
Die Erfindung betrifft eine Wechselrichteranordnung mit Flüssigkeitsstrahlwechselrichter, vorzugsweise mit Kontaktüberlappung und gleichstromseitiger Drossel. Ein wichtiges Problem ist die Konstanthaltung der Wechselrichterausgangsspannung auch bei schwankender Batteriespannung. Speist man auch den Antriebsmotor für die die Kontaktgabe besorgende Flüssigkeitszentrifuge aus der Batterie, so ist Spannungskonstanthaltung mit Drosseln und Kondensatoren, also durch entsprechende Bemessung der Siebkreise und auf Kosten des Leistungsfaktors, durchzuführen.The invention relates to an inverter arrangement with a liquid jet inverter, preferably with contact overlap and DC-side choke. An important problem is that Keeping the inverter output voltage constant even if the battery voltage fluctuates. One eats also the drive motor for the liquid centrifuge providing the contact from the battery, like that is voltage stabilization with chokes and capacitors, i.e. by appropriate dimensioning of the Filter circles and at the expense of the power factor.
Es wurde bereits vorgeschlagen, Kohledruckregler oder magnetische Verstärker hinter den Wechselrichterausgang zu schalten. Das führt zwar grundsätzlich zum Ziel, bedeutet aber zusätzlichen Aufwand und verschlechtert wegen der nie ganz vermeidbaren Verluste ebenfalls den Leistungsfaktor. Außerdem ist noch nichts für die Frequenzkonstanthaltung getan, was durch zusätzliche Maßnahmen zu erreichen ist. Es ist bereits vorgeschlagen, bei geregelter Ausgangswechselspannung den Motor im stationären Betrieb über Gleichrichter aus dieser Wechselspannung zu speisen. Damit ist das Problem der Frequenzkonstanthaltung auf die Regelung der Wechselrichterausgangsspannung zurückgeführt, was also damit zentrales Problem bleibt.It has already been suggested to put carbon pressure regulators or magnetic amplifiers behind the inverter output to switch. Although this basically leads to the goal, it means additional effort and also worsens the power factor because of the losses that can never be completely avoided. Also is Nothing has yet been done to maintain a constant frequency that can be achieved through additional measures. It has already been proposed to run the motor in steady-state operation with a regulated AC output voltage to feed from this AC voltage via rectifier. So the problem is keeping the frequency constant traced back to the regulation of the inverter output voltage, so what is central Problem remains.
Vorliegende Erfindung weist nun einen sehr einfachen Weg, der außerdem die kleinstmöglichen Verluste bedeutet. Es wird vorgeschlagen, den Wechselrichtertransformator als Sättigungstransformator auszubilden. The present invention now shows a very simple way, which also has the smallest possible losses means. It is proposed to design the inverter transformer as a saturation transformer.
Die Zeichnung zeigt beispielsweise eine Schaltung gemäß der Erfindung (Fig. 1), die an Hand der Diagramme der Fig. 2 bis 4 erläutert wird.The drawing shows, for example, a circuit according to the invention (FIG. 1), which is based on the Diagrams of Figs. 2 to 4 will be explained.
Mit 1 ist schematisch das Flüssigkeitsstrahlstromrichtergefäß angedeutet, das die Spannung einer Batterie 2 mit wechselnder Richtung an die Primärwicklung 3 eines Sättigungstransformators 4 legt. Mit 5 ist die Sekundärwicklung bezeichnet.With 1 is the liquid jet converter vessel schematically indicated that the voltage of a battery 2 with alternating direction to the primary winding 3 of a saturation transformer 4 sets. The secondary winding is denoted by 5.
Fig. 2 zeigt nun den Fall, daß die Batteriespannung (Uß) etwas zu klein ist (UBt). Die von dem Transformator
aufnehmbare Spannungszeitfläche reicht gerade bis zum Stromnulldurchgang, wobei nach Art
einer Zwangskommutierung die Spannung umgepolt Wechselrichteranordnung
mit FlüssigkeitsstrahlwechselrichterFig. 2 now shows the case that the battery voltage (Uß) is somewhat too small (U Bt ). The voltage-time area that can be absorbed by the transformer just extends to the current zero crossing, the voltage being reversed in the inverter arrangement in the manner of forced commutation

wird. Die von den beiden Drosseln 6 und 7 aufgenommene Spannung verschwindet. Fig. 3 zeigt den Fall etwas zu großer Batteriespannung (Ug2). Die Spannungszeitfläche, die der Transformator aufnehmen und praktisch allein auch wieder abgeben kann, bleibt konstant, so daß nun die beiden Drosseln, wie Fig. 4 zeigt, einen Teil der Spannung aufnehmen müssen. In beiden Fällen bleibt die Sekundärspannung als Rechteckspannung in konstanter Höhe und konstanter Dauer erhalten.will. The voltage picked up by the two chokes 6 and 7 disappears. Fig. 3 shows the case of a somewhat too high battery voltage (Ug 2 ). The voltage-time area that the transformer can absorb and, practically alone, can also output again remains constant, so that the two chokes, as shown in FIG. 4, now have to absorb part of the voltage. In both cases, the secondary voltage is retained as a square wave voltage at a constant level and constant duration.
