Anordnung und Verfahren zur potentialgetrennten Ubertragung von Gleich- und Wechselstromsignalen. Die Signale konnen in beide Richtungen uber den gleichen und einzig vorhandenen galvanisch getrennten Kanal ubertragen werden. Die Anordnung umfasst ein erstes Sende- und Empfangssystem (1), einen Stromwandler (4) im Kurzschlussbetrieb, eine Operationsverstarkeranordnung (5) und ein zweites Sende- und Empfangssystem (2) mit Meldesignalgeber (9).read more

Björn Haase,Bernd Maringer +1 more
TL;DR: In this paper, a method for signal transmission between a first and a second system (S1, S2) that are interconnected by means of a current loop (L) was proposed.
Patent
Method for signal transmission between process control systems of e.g. field device for detecting process variable in process automation industry, involves adjusting direct current signal and alternating current signal in current loop
TL;DR: In this paper, a data stream is transmitted to a power output circuit, which converts the transmitted data stream into the direct current signal and the alternating current signal by a current output circuit.

Circuit arrangement for floating signal transmission
TL;DR: In this article, a conventional transformer is used to transmit the signals from an electronics section to a power output stage, and feedback signals relating to defects are transmitted in the reverse direction from the same transformer to an evaluating circuit (9, 5, 6, 7, 8).
Patent
Circuit arrangement having a DC isolator for analog DC signals
TL;DR: In this paper, the authors proposed a DC isolator which operates without any feedback effect and in which, in the secondary circuit, a free-running oscillator is arranged, which is damped by the load.
Patent
Wide band frequency input transformer - has input impedance and amplifier across its output terminals
TL;DR: In this paper, an assembly consisting of two series impedances (3,4), the transformer (1) and an amplifier (2) is used to improve the parameters and increase the frequency band of an input transformer used in telecommunication units.
Patent
Circuit structure for electroplate-separated transmission of an analog input quantity uses a signal transmission component with voltage input/output to adapt voltage between input/output
TL;DR: In this article, a signal transmission component (STC) is designed as an inductive STC (6), and a circuit structure has a charging/discharging structure with a switch element (S1) so that, by operating the switch element, charging (I1) or discharging (I2) currents arise that are proportional to an input voltage (U1) and flow through the inductive StC while an output voltage(U3) adjusts at a voltage output.
