Patent number: 9742269Abstract: A voltage control circuit for electrically coupling a field device coupler to a bus line. 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.Type: GrantFiled: November 12, 2015Date of Patent: August 22, 2017Assignee: R.
