An input voltage (UE) provided at the voltage control circuit by the bus line is converted into an output voltage (UA) that can be regulated and limited. If a current limitation is additionally provided, the “inherent safety” ignition protection type can be achieved. The voltage control circuit has a chopper-type regulator without galvanic isolation. A parallel path is formed parallel to the chopper-type regulator by a series connection of two buffer capacitors. Communication signals of higher frequency can be transmitted past the chopper-type regulator via the parallel path. The parallel path and a reference terminal of the chopper-type regulator are additionally connected via an impedance circuit to a reference potential at a second input terminal of the voltage control circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Voltage control circuit for a field device coupler","description":"A voltage control circuit for electrically coupling a field device coupler to a bus line.
