ω Cω C
Die Punkte 3, 4 und 5, an denen sich die beiden eingetragenen Spannungskurven schneiden, sind mögliehe Arbeitspunlite des Schwingkreises, wobei die Schnittpunkte 3 und 4 stabile Arbeitspunkte darstellen und der Schnittpunkt 5 einen instabilen Arbeitspunkt bezeichnet, wie von der Theorie der nichtlinearen Rescnanzkreise her bekannt ist.Points 3, 4 and 5, at which the two voltage curves entered intersect, are possible Working point of the oscillating circuit, where the intersection points 3 and 4 represent stable working points and the intersection point 5 denotes an unstable working point, as from the theory of the nonlinear Circles of resonance is known.
In F i g. 3 ist der Betrag der Drossels^/annung UL in Abhängigkeit von der Induktivität L der Drossel in einem nichtlinearen gedämpften Schwingkreis dargestellt. Diese Kennlinie 6 ist ebenfalls von der Theorie der nichtlinearen Schwingkreise her bekannt. Die mit einer durchgehenden Linie gezeichneten Teile der Kennlinie 6 bezeichnen den stabilen Bereich, während der mit einer gestrichelten Linie gezeichnete Kurvenzweig einen instabilen Bereich der Kennlinie darstellt.In Fig. 3 shows the amount of the throttle ^ / annung U L as a function of the inductance L of the throttle in a non-linear damped resonant circuit. This characteristic curve 6 is also known from the theory of non-linear oscillating circuits. The parts of the characteristic curve 6 drawn with a continuous line denote the stable region, while the branch of the curve drawn with a dashed line represents an unstable region of the characteristic curve.
An Hand der beiden Diagramme läßt sich die Wirkungsweise der Einrichtung gemäß der vorliegenden Erfindung erläutern. Angenommen, der Schwingkreis befindet sich in seinem stabilen Arbeitspunkt 3 (F i g. 2), dann kann beispielsweise durch eine Anhebung der an den Schwingkreis angelegten Spannung U0, die eine Verschiebung der linearen Kennlinie 2 in die gestrichelt dargestellte Lage 2' bewirkt, der Schwingkreis in einen Zustand gebracht werden, in welchem er nur noch einen einzigen stabilen Arbeitspunkt 4' hat. Der Schwingkreis kippt daher in den Arbeitspunkt 4'. Dieser Arbeitspunkt hat einen höheren Strom / als der Arbeitspunkt 3. Dadurch kann parallel zu irgendeinem Element des Schwingkreises eine höhere Spannung abgegriffen werden, mit der sich eine nachgeschaltete elektronische Schaltstufe oder Schaltwerke steuern lassen.The mode of operation of the device according to the present invention can be explained with the aid of the two diagrams. Assuming that the resonant circuit is at its stable operating point 3 (FIG. 2), then, for example, by increasing the voltage U 0 applied to the resonant circuit, which causes a shift of the linear characteristic curve 2 into the position 2 'shown in dashed lines, the resonant circuit can be brought into a state in which it only has a single stable operating point 4 '. The resonant circuit therefore tilts into the operating point 4 '. This operating point has a higher current / as the operating point 3. As a result, in parallel with any element of the resonant circuit, a higher voltage can be tapped off, can be controlled with a downstream electronic Schaltstu f e or derailleurs.
Ein Kippen des Schwingkreises in eine andere stabüe Lage mit geändertem Stromwert kann auch durch eine Änderung der Kapazität C oder der Kreisfrequenz ω der angelegten Spannung U0 bewirkt werden, wodurch eine Änderung des Steigungswinkels « der linearen Kennlinie 2 erreicht wird.A tilting of the resonant circuit into another stable position with a changed current value can also be caused by a change in the capacitance C or the angular frequency ω of the applied voltage U 0 , whereby a change in the slope angle of the linear characteristic curve 2 is achieved.
Gemäß der Erfindung wird jedoch das Kippen desAccording to the invention, however, the tilting of the
jo Resonanzkreises durch eine Veränderung der Induktivität L des Schwingkreises bewirkt. Durch eine Vormagnetisierung der Drossel wird der Verlauf der Kennlinie 1 beeinflußt, und man erhalt eine Kennlinie 1', die nunmehr einen einzigen stabilen Zustandjo resonance circuit by changing the inductance L of the resonant circuit causes. By a pre-magnetization the throttle, the course of the characteristic curve 1 is influenced, and a characteristic curve is obtained 1 ', which is now a single stable state
des Resonanzkreises erlaubt. Bei einer Änderung der Kennlinie 1 in die Kennlinie 1' kippt der Schwingkreis von dem stabilen Arbeitspunkt 3 in den Arbeitspunkt 4", in welchem ein höherer Strom fließt als im Arbeitspunkt 3.of the resonance circuit allowed. When characteristic curve 1 changes to characteristic curve 1 ', the oscillating circuit tilts from the stable operating point 3 to the operating point 4 ″, in which a higher current flows than in the Working point 3.
Das Verhalten der Drosseln unter dem Einfluß der Änderung der magnetischen Durchflutung laßt sich aus Fio 3 ersehen. Die Drossel weist zunächst eine Induktivität L0 auf und befindet sich damit im Zustand eines kleinen Stromes /, entsprechend demThe behavior of the chokes under the influence of the change in the magnetic flow can be seen from FIG. The choke initially has an inductance L 0 and is thus in the state of a small current /, corresponding to the
•25 Arbeitspunkt 3 in F i g. 2. Mit Hilfe eines Permanentmagneten M, der an die Drossel L herangebracht wird, läßt sich dann die Induktivität der Drossel beispielsweise bis auf einen Wert L1 (Fig. 3) verringern. Dabei kippt der nichtlineare Schwingkreis um die• 25 working point 3 in FIG. 2. With the aid of a permanent magnet M, which is brought up to the choke L, the inductance of the choke can then be reduced, for example, to a value L 1 (FIG. 3). The non-linear oscillating circuit tips around the
Kante 7 der Kennlinie 6 in den oberen Zweig der Kennlinie mit einem höheren Strom und einer höheren Spannung um. Diesem Kippen entspricht die Umstellung des Resonanzkreises vom Arbeitspunkt 3 auf seinen Arbeitspunkt 4 oder 4" in Fig. 2. WirdEdge 7 of the characteristic 6 in the upper branch of the characteristic with a higher current and a higher one Tension around. The changeover of the resonance circuit from operating point 3 corresponds to this tilting to its working point 4 or 4 "in Fig. 2. Will
die Vormagnetisierung durch den Permanentmagneten wieder entfernt, so erhält man wieder die ursprüngliche Induktivität L0, und der Kreis kippt um die Kante 8 wieder in den Zustand kleinen Stromes um. Das Kippen um die Kanten 7 und 8 kann sehr rasch vor sich gehen.If the premagnetization is removed again by the permanent magnet, the original inductance L 0 is obtained again, and the circle tips around the edge 8 again into the state of low current. The tilting around the edges 7 and 8 can take place very quickly.
