Description

Anordnung zur Erzeugung von Wechselströmen vorgegebener Kurvenform ES ist bekannt, Wechselströme einer vorgeschriebenen Kurvenform dadurch zu erzeugen, daß man eine Wechselspannung leicht herstellb.arer Kurvenform, z. B. Sinusform, durch ein Organ von geeigneter Stromspannung-Charakteristik hindurchschickt und dadurch verzerrt. So kann man z. B. Sinushalbwellen mit Hilfe eines linearen Gleichrichters erzeugen, trapezförmige Wechselstromkurven mit Hilfe eines Organs, das eine Sättigungsstrom-Charakteristik hat, periodische Stromspitzen mit Hilfe eines Organs, dessen Charakteristik nur in einem schmalen Intervall von Null verschiedene Werte aufweist usw. Bei höheren Frequenzen oder bei Verwendung bestimmter Organe, wie z.B. elektrolytischer Gleichrichter, entsteht nun dadurch eine Schwierigkeit, daß durch die Kapazität des verzerrenden Organs ein Wechselstrom hindurchfließt, der sich dem durch die Charakteristik des Organs bedingten Strom überlagert und, dadurch eine andere. als die gewünschte Form entstehen läßt.Arrangement for generating alternating currents with a given curve shape It is known to generate alternating currents with a prescribed curve shape by that an alternating voltage can easily be produced in a curve shape, e.g. B. Sinusoid, through an organ of suitable voltage characteristic and distorted thereby. So you can z. B. Half-sine waves using a linear rectifier generate trapezoidal alternating current curves with the help of an organ that has a saturation current characteristic has, periodic current peaks with the help of an organ whose characteristic only has values other than zero in a narrow interval, and so on Frequencies or when using certain organs, such as electrolytic rectifiers, A difficulty arises because of the capacity of the distorting An alternating current flows through the organ, which is due to the characteristics of the Organ-related current superimposed and, thereby, another. than the shape you want can arise.

Erfindungsgemäß wird daher die Kapazität des verzerrenden Organs durch Hilfskapazitäten kompensiert, so daß die kapazitiven Ströme nicht mehr in den Verbraucher gelangen können und die Kurvenform des Nutzstromes wirklich der statischen Charakteristik des verzerrenden Organs entspricht.According to the invention, therefore, the capacity of the distorting organ is through Auxiliary capacities compensated, so that the capacitive currents no longer in the consumer and the curve shape of the useful current really depends on the static characteristics of the distorting organ.

In der Abbildung ist ein Ausführungsbeispiel dargestellt. Hierin bedeutet i die Wechselstromquelle, ä das verzerrende Organ, 3 die Kompensationskapazität, q. und 5 beliebige, aber untereinander gleichartige Widerstände (Ohmsche Widerstände, Kapazitäten, Selbstinduktionen oder Kombinationen davon), deren Verhältnis gleich ist dem Verhältnis der Kapazitäten von 2 und 3. Hierdurch wird erreicht, daß durch den Verbraucher 6 ein Strom fließt, der lediglich durch- die statische Charakteristik des Organs 2 bestimmt ist und durch die Kapazität dieses Organs nicht mehr beeinflußt wird.An exemplary embodiment is shown in the figure. Herein means i the alternating current source, ä the distorting organ, 3 the compensation capacity, q. and any 5 resistors of the same type (ohmic resistances, Capacities, self-inductions or combinations thereof), their ratio is the same is the ratio of the capacities of 2 and 3. This achieves that by the consumer 6 flows a current that only through the static characteristic of organ 2 is determined and no longer influenced by the capacity of this organ will.

Der Erfindungsgegenstand kann für alle geeigneten Zwecke Anwendung finden. Beispielsweise können die erfindungsgemäß mit einer bestimmten gewünschten Kurvenform erzeugten Wechselströme zur Steuerung von Fernsehgeräten oder Bildübertragungsapparaten dienen. Auch die elektrische Musikerzeugung ist als Anwendungsgebiet besonders zu erwähnen.The subject matter of the invention can be used for all suitable purposes Find. For example, the invention with a certain desired Waveform generated alternating currents for controlling television sets or image transmission apparatus to serve. Electric music production is also a particular area of application mention.
