Description

Der Innenwiderstand von Netzgeräten und anderen Spannungsquellen kann nicht beliebig klein gemacht werden. Infolgedessen haben die bekannten Spannungsquellen den Nachteil, daß die Klemmenspannung mit wachsender Stromentnahme abnimmt. Für viele Anwendungszwecke ist jedoch eine möglichst konstante- Klemmenspannung erwünscht.The internal resistance of power supply units and other voltage sources can cannot be made arbitrarily small. As a result, the known voltage sources the disadvantage that the terminal voltage decreases with increasing current consumption. For For many applications, however, a terminal voltage that is as constant as possible is desired.

Erfindungsgemäß wird dies dadurch erreicht, daß in den Spannungsquellenstromkreis eine Gleichrichteranordnung in Form einer Selengleichrichteranordnung oder einer Kupfersulfidgleichrichteranordnung oder einer Gas- oder Dampfgleichrichteranordnung gelegt ist, deren Widerstand sich umgekehrt proportional zur entnommenen Stromstärke derart ändert, daß die Klemmenspannung konstant oder annähernd konstant bleibt.According to the invention this is achieved in that in the voltage source circuit a rectifier arrangement in the form of a selenium rectifier arrangement or a Copper sulfide rectifier arrangement or a gas or steam rectifier arrangement is placed, the resistance of which is inversely proportional to the current strength drawn changes in such a way that the terminal voltage remains constant or approximately constant.

Es ist besonders zweckmäßig, als Gleichrichteranordnung, d. h. als Widerstand mit fallender Stromstärkenkennlinie, Gas- oder Dampfgleichrichtenöhren zu verwenden, die eine stromabhängige Brennspannung besitzen. Für "geringe Ströme bis zu 3o mA besitzen auch Selengleichrichter eine Kennlinie, die für Stromkreise gemäß der Erfindung geeignet ist, während für große Ströme bis zu einem Amp. Kupfersulfidgleichrichtersäulen verwendet werden können. Besonders zweckmäßig ist es, die Gleichrichteranordnungen nach der Erfindung mit geeigneten Ktihlinitteln zu versehen, welche eine entsprechende Kennlinie erzeugen.It is particularly useful as a rectifier arrangement, i. H. as Resistance with falling current characteristic, gas or steam rectifier tubes to use that have a current-dependent operating voltage. For "low currents up to 30 mA, selenium rectifiers also have a characteristic curve that is used for electrical circuits according to the invention is suitable, while for large currents up to one amp. copper sulfide rectifier columns can be used. It is particularly useful to use the rectifier arrangements to provide according to the invention with suitable refrigerants which have a corresponding Generate characteristic.

An Hand der Zeichnung, in der ein Ausführungsbeispiel der Erfindung dargestellt ist, sei der Erfindungsgedanke näher erläutert.With reference to the drawing, in which an embodiment of the invention is shown, the inventive concept will be explained in more detail.

In Fig. i ist ein Verbraucherstromkreis mit einer e Volt liefernden Spannungsquelle E, Innenwiderstand Ri und Außenwiderstand Rd gezeichnet. Die entstehende Stromstärke ist j. Erfindungsgemäß ist in den Stromkreis ein Widerstand R" gelegt, der sich umgekehrt proportional mit dem durchfließenden Strom ändert. Die- Spannung Ua am. Verbrauchswiderstand Ra berechnet sich dann nach der Formel Es sei angenommen, daß ist. Erfindungsgemäß wird gewählt. Hierbei bedeuten a und b Konstanten. In Fig. I, a consumer circuit is drawn with a voltage source E delivering e volts, internal resistance Ri and external resistance Rd. The resulting current is j. According to the invention, a resistor R ″ is placed in the circuit, which changes inversely proportional to the current flowing through it. The voltage Ua at the consumption resistance Ra is then calculated according to the formula Assume that is. According to the invention is chosen. Here a and b mean constants.

Dann ist Diese Formel zeigt, daß die Änderung der Arbeitsspannung Ua um so kleiner ist, je kleiner das Produkt Ri - j gegen den konstanten Betrag b ist.Then This formula shows that the change in the working voltage Ua is smaller, the smaller the product Ri - j against the constant amount b.

. In Fig. 2 ist ein Schaltbild dargestellt, mit dem sich der Erfindungsgedanke beispielsweise verwirklichen läßt. Die Gleichrichteranordnung Gl besteht aus den erwähnten speziellen Gleichrichtern und ist in den Innenkreis der Stromquelle eingeschaltet.. In Fig. 2 a circuit diagram is shown with which the inventive concept for example can be realized. The rectifier arrangement Gl consists of the mentioned special rectifiers and is switched into the inner circuit of the power source.
