Description
in den letzten Jahren ist das Interesse für die -Ver= wendbarkeit magnetischer Verstärker gewachsen. Die hier gewonnenen Erfahrungen, Ergebnisse usw. gelten jedoch nur für rein Ohmsche Verbraucher, d. h. Verbraucher, bei denen Spannungs- und Stromkurve zeitlich zur Deckung zu bringen sind. Häufig besteht aber der Wunsch, magnetische Verstärker in Verbindung mit Verbrauchern mit induktivem Anteil, z. B. Relais, Verstellmotoren usw., zu verwenden. Dies ist jedoch nicht ohne weiteres möglich, da die Charakteristiken der magnetischen Verstärker flacher und damit praktisch unbrauchbar werden. Die Parallelschaltung eines einfachen Kondensators führt nicht zum Ziel, da es kein einfachfrequenter Vorgang ist. Erfindungsgemäß gelingt die Anwendung der magnetischen Veistärker bei Verbrauchern mit induktivem Anteil dadurch, daß parallel zu dem aus R und L bestehenden Verbraucher ein weiterer, aus R und C bestehender Verbraucher geschaltet ist, und daß die Beziehung wenigstens angenähert erfüllt ist.In the last few years there has been a growing interest in the applicability of magnetic amplifiers. The experiences, results, etc. gained here only apply to purely ohmic consumers, ie consumers where the voltage and current curves are to be brought to congruence over time. However, there is often a desire to use magnetic amplifiers in conjunction with consumers with an inductive component, e.g. B. relays, adjusting motors, etc. to use. However, this is not easily possible since the characteristics of the magnetic amplifiers become flatter and thus practically unusable. The parallel connection of a simple capacitor does not achieve the goal, since it is not a single-frequency process. According to the invention, the use of magnetic amplifiers in consumers with an inductive component is achieved in that a further consumer consisting of R and C is connected in parallel with the consumer consisting of R and C, and that the relationship is at least approximately fulfilled.
In der Zeichnung ist die Erfindung veranschaulicht. Der vereinfacht dargestellte magnetische Verstärker V speist einen Verbraucher, der außer seinem Ohmschen Anteil R einen induktiven Anteil L aufweist. Erfindungsgemäß ist ein weiterer Verbraucher parallel zu dem ersten Verbraucher geschaltet, der gleichen Ohmschen Anteil R und außerdem einen kapazitiven Anteil C hat, dessen Größe wenigstens angenähert der Beziehung genügt. Durch die Hinzufügung eines zweiten Verbrauchers gelingt es, die ursprünglichen Charakteristiken wiederherzustellen, d. h. der gesamte Verbraucher hat bei allen Frequenzen einen Ohmschen Charakter.The invention is illustrated in the drawing. The magnetic amplifier V, shown in simplified form, feeds a load which, in addition to its ohmic component R, has an inductive component L. According to the invention, a further consumer is connected in parallel to the first consumer, which has the same ohmic component R and also a capacitive component C, the size of which at least approximates the relationship enough. The addition of a second consumer makes it possible to restore the original characteristics, ie the entire consumer has an ohmic character at all frequencies.
Zum Stand der Technik sei noch vermerkt, daß die in der Erfindung angegebene Bemessung für R, L und C an sich im Schrifttum bekannt ist und meistenteils mit Widerstandsresonanz bezeichnet wird. Diese Bemessung hatte zwar eine grundsätzliche, aber geringfügige praktische Bedeutung, und es bedurfte umständlicher Überlegungen, daß gerade die Anordnung der Widerstandsresonanz den Veiwendungsbereich der magnetischen Verstärker erheblich erweitern würde.Regarding the prior art, it should also be noted that in the invention specified dimensioning for R, L and C is known in the literature and mostly is referred to as resistance resonance. This dimensioning had a fundamental, but insignificant practical importance, and it required cumbersome considerations, that it is precisely the arrangement of the resistance resonance that limits the area of application of the magnetic Amplifier would expand significantly.
Im Sinne der Erfindung kann man vorteilhaft Elektrolytkondensatoren anwenden, weil diese bekanntlich mit verhältnismäßig wenig Aufwand große Kapazitäten ermöglichen. Jedoch ist dabei darauf zu achten, daß, besonders bei Teilaussteuerung, der Anteil der Ausgangswechselspannung (doppelte Amplitude) nicht größer als der Anteil der Ausgangsgleichspannung ist. Die Erfindung ist auch anwendbar bei solchen Anordnungen, bei denen der Verbraucher außer dem Ohmschen Anteil auch einen kapazitiven Anteil hat. Sinngemäß muß dann der zweite Verbraucher einen induktiven Anteil haben.For the purposes of the invention, electrolytic capacitors can advantageously be used apply because they are known to have large capacities with relatively little effort enable. However, it must be ensured that, especially with partial modulation, the proportion of the output alternating voltage (double amplitude) is not greater than that Is the proportion of the DC output voltage. The invention is also applicable to such Arrangements in which the consumer also has a capacitive component in addition to the ohmic component Share. The second consumer must then have an inductive component.
