Description

Hallgenerator mit induktionsfreiem Hallkreis Es sind verschiedene technische Anwendungen des Halleffektes, insbesondere in der elektrischen Meß-, Steuer- und Regeltechnik vorgeschlagen worden. Hall generator with induction-free Hall circuit There are different technical applications of the Hall effect, especially in electrical measurement, Control technology has been proposed.

Für Hallanordnungen, die in Verbindung mit einem zeitlich veränderlichen Magnetfeld arbeiten, ist zur Beseitigung der im Hallkreis auf tretenden Induktionsspannungen angegeben worden, die Zuleitung zu einer der Hallelektroden zweifach anzuordnen, so daß zu jedem Leitungsstück ein gleich großes, den gleichen Induktionsstrom in entgegengesetzter Richtung füh rendes Leitungsstück vorliegt. For reverb arrangements that are used in conjunction with a time-varying Working magnetic field is to eliminate the induction voltages occurring in the Hall circuit has been specified to arrange the supply line to one of the Hall electrodes twice, so that an induction current of the same size in opposite direction leading line section is present.

Beim Hallgenerator gemäß der Erfindung ist die durch die angegebene Maßnahme erreichte Induktionskompensation noch erheblich verfeinert; dies ist von besonderer Bedeutung bei sehr empfindlichen Meß Steuer- oder Regeleinrichtungen. Die Lösung besteht darin, daß in einer der Zweifachleitungen des wie oben angegeben ausgeführten Hallkreises ein einstellbarer Widerstand vorgesehen ist. Hierdurch ist eine Feinabgleichung auftretender Induktionsspannungen möglich. Es ist zweckmäßig, diesen Widerstand außer halb des Wirkungsbereiches des veränderlichen Magnetfeldes anzuordnen und mit einer induktionsfreien, vorzugsweise verdrillten Zu- und Rückleitung zu versehen. When the Hall generator according to the invention is indicated by the Measure achieved induction compensation still considerably refined; this is from of particular importance in the case of very sensitive measuring control or regulating devices. The solution is that in one of the dual lines of the as indicated above executed Hall circuit an adjustable resistor is provided. Through this a fine adjustment of occurring induction voltages is possible. It is appropriate this resistance outside half of the effective range of the variable magnetic field to be arranged and with an induction-free, preferably twisted supply and return line to provide.

Ein Ausführungsbeispiel des Hallgenerators gemäß der Erfindung ist in der Zeichnung dargestellt. Der Halbleiterkörper ist mit 1, die Hallelektroden sind mit 2 und 3 und deren Elektrodenzuführungen mit 4 und 5 bezeichnet. Die Zuführung 5 besteht aus den Teilzuführungen 5 und 5 b. Diese sind in der durch den Halbleiterkörper vorgegebenen Ebene, die vorzugsweise senkrecht zur Magnetfel drichtung liegt, um den Halbleiterkörper herumgeführt. In der Teilzuführung5a ist der einstellbare niederohmige Widerstand 6 angeordnet; mit diesem erfolgt die Feinkompensation der unter dem Einfluß des veränderlichen Magnetfeldes im Hallkreis auftretenden Induktionsspannungen. Die Elektroden für den Primärstrom bzw. deren Zuführungen sind mit 7 und 8 angegeben. An embodiment of the Hall generator according to the invention is shown in the drawing. The semiconductor body is with 1, the Hall electrodes are designated with 2 and 3 and their electrode leads with 4 and 5. The feed 5 consists of the partial feeders 5 and 5 b. These are in the through the semiconductor body predetermined plane, which is preferably perpendicular to the Magnetfel direction to led around the semiconductor body. In the part feed 5a is the adjustable low-resistance Resistor 6 arranged; with this the fine compensation takes place under the influence of the variable magnetic field occurring in the Hall circuit. The electrodes for the primary current and their supply lines are indicated by 7 and 8.
