Patent number: 10181789Abstract: Provided is a signal isolator with reduced power loss. The signal isolating circuit comprises an input stage and an output circuit that is connected downstream thereof and which includes a linear regulator. The linear regulator comprises an operational amplifier and a switching regulator, wherein an input of the switching regulator is connected to an output of the operational amplifier and an output of the switching regulator is fed back to a first input of the operational amplifier. The operational amplifier regulates the switching regulator such that the switching regulator provides at its output an output measuring signal for a load that corresponds to the input measuring signal.Type: GrantFiled: January 22, 2015Date of Patent: January 15, 2019Assignee: Phoenix Contact GmbH & Co. KGInventor: Heinz-Wilhelm Meier

Patent number: 9946280Abstract: The invention relates to a current output stage (100) comprising an input (IN), an output (OUT) for connecting to an input of a unit (200) to be supplied with current, a control stage (T1, T2, Z1), which sets the output current (Iout), and an energy supply stage (Uv;Uv,?Uv), which can provide energy for the output current (Iout). The current output stage (100) comprises a first transistor (T1), which controls the output current in a closed-loop in the passive operating mode, and the current output stage (100) contains a second transistor (T2; T2, T3), which controls the output current (Iout) in a closed-loop in the active operating mode, wherein the first transistor (T1) and the second transistor (T2; T2, T3) is controlled by a control stage OP1) in an open loop, and wherein in the active operating mode the energy supply stage (Uv;Uv,?Uv) is controlled in an open loop such that same provides energy for the output current (Iout).Type: GrantFiled: October 13, 2011Date of Patent: April 17, 2018Assignee: Phoenix Contact GMBH & Co.

Patent number: 7391252Abstract: A circuit arrangement in which the temperature dependency of the short-circuit current and/or the influence of the output signal by the load current are at least partially avoided has first and second input connections, first and second output connections, a supply voltage connection as well as with a voltage-controlled voltage source, an output stage and a short-circuit protective circuit, whereby the output signal from an input voltage applied to input connections is generated via voltage-controlled voltage source and output stage. The circuit arrangement is characterized in that a voltage sequencing circuit and a shunting resistor connected in parallel to voltage sequencing circuit are part of the short-circuit protective circuit and in that a parallel circuit formed of the voltage sequencing circuit and a shunting resistor is connected to the second output connection and second input connection.Type: GrantFiled: October 31, 2005Date of Patent: June 24, 2008Assignee: Phoenix Contact GmbH & Co.
