Patent number: 10277534Abstract: A system may receive, by a switching component of the system, network traffic to be provided to an I/O component of the network device. The system may route, by the switching component, the network traffic to the I/O component based on whether the I/O component is connected to the switching component via the first connections and/or via second connections. The first connections may be connections via a chassis of the system. The second connections may be connections via a connector component that is removable from the switching component. The network traffic may be routed via the first connections and the second connections when the I/O component is connected via the first connections and the second connections. The network traffic may be routed via the first connections and not via the second connections when the I/O component is connected via the first connections and not via the second connections.Type: GrantFiled: June 1, 2016Date of Patent: April 30, 2019Assignee: Juniper Networks, Inc.Inventors: John Kenney, Christopher Otte, Bhavesh Patel, Valery Kugel, Muhammad Sagarwala

Patent number: 9981561Abstract: A motor vehicle electrical system which includes an electric machine, an active bridge rectifier, and at least one control device, the at least one control device being configured for converting an alternating voltage which is output by the electric machine at a number of phase connections into a direct voltage by controlling active switching elements of the bridge rectifier. An arrangement is provided configured for initiating a short circuit of at least two of the phase connections as soon as a signal characterizing the direct voltage exceeds an upper threshold value, and for deactivating the short circuit as soon as the signal characterizing the direct voltage subsequently falls below a lower threshold value. An evaluation device is provided configured for detecting a value of the direct voltage, for filtering the detected value, and for providing the filtered value as the signal characterizing the direct voltage.Type: GrantFiled: November 7, 2014Date of Patent: May 29, 2018Assignee: SEG Automotive Germany GmbHInventors: Christopher Otte, Paul Mehringer, Wolfgang Feiler

Patent number: 9985625Abstract: A method for controlling a bridge rectifier which includes active switching elements is provided, in which, during normal operation, at least one of the active switching elements is controlled using a voltage signal, the voltage of which is changed from a first voltage value to a second voltage value within at least one switching time. The at least one switching time is extended by a predefinable time period if load shedding at the bridge rectifier is determined. Also described is a corresponding rectifier system and a computer program product.Type: GrantFiled: July 31, 2013Date of Patent: May 29, 2018Assignee: SEG Automotive Germany GmbHInventors: Paul Mehringer, Christopher Otte

Patent number: 9985517Abstract: A rectifier module for an active bridge rectifier having two switching elements, connected in series between two end terminals, and between which a center tap is formed, and a control circuit including a monitoring unit, a synchronization unit, and a control unit, the monitoring unit detecting a measuring voltage and outputting a request signal when the measuring voltage exceeds an upper threshold value. The synchronization unit outputs a synchronization signal to a synchronization terminal as long as the monitoring unit outputs the request signal, and otherwise to monitor the synchronization terminal for a synchronization signal. The control unit switches one of the two switching elements into a conductive state at least in sections during an activation period of time, when the monitoring unit outputs the request signal and/or when the synchronization signal is detected and is optionally recognized as valid by the monitoring.Type: GrantFiled: July 28, 2014Date of Patent: May 29, 2018Assignee: SEG Automotive Germany GMBHInventors: Harald Schueler, Siegbert Sautter, Christopher Otte, Paul Mehringer, Jie Ge, Wolfgang Feiler, Matthias Schmidt

Patent number: 9950626Abstract: A bridge rectifier having AC voltage terminals, two DC voltage terminals, and a number of half-bridges corresponding to the number of AC voltage terminals. Each half-bridge has two activatable switching elements, connected in series between the DC voltage terminals and between which one of the AC voltage terminals is connected in each case. Each half-bridge includes a control circuit configured to detect an output voltage applied between the DC voltage terminals and switch a first switching element of the two switching elements of the particular half-bridge to be conductive by activation using a first control signal until the output voltage falls below a lower threshold value, after it has previously exceeded an upper threshold value, and to activate it in a clocked manner by activation using a second control signal, until the output voltage exceeds the upper threshold value, after it has previously fallen below the lower threshold value.Type: GrantFiled: June 24, 2014Date of Patent: April 24, 2018Assignee: SEG Automotive Germany GmbHInventors: Christopher Otte, Paul Mehringer

Publication number: 20160294181Abstract: A method for operating a motor vehicle electrical system which includes an electric machine, and an active bridge rectifier connected to the electric machine via phase connections. After the bridge rectifier has been operated at least once in a short circuit operating mode, a determination is made, based on at least one feature of a signal which characterizes a voltage that drops between the direct voltage terminals of the bridge rectifier, whether the signal has exceeded the upper threshold value due to a cable break at at least one of the direct voltage terminals. If so, the bridge rectifier is subsequently operated in the short circuit operating mode for an extended period of time, and/or a control signal having a second switching time greater than that in the first method phase is used for controlling the active switching elements.Type: ApplicationFiled: November 10, 2014Publication date: October 6, 2016Inventors: Christopher OTTE, Paul MEHRINGER
