Patent number: 10615107Abstract: A power electronic switching device having plurality of potential surfaces. At least two different potentials are respectively assigned to at least one of the potential surfaces. A plurality of semiconductor components are arranged in an n×m matrix, oriented in the x-y-direction, on a first conductor track, formed by at least one potential surface of the first potential. The semiconductor components are connected in parallel with one another and form a current valve. In this case, the semiconductor components can be distributed among a plurality of potential surfaces of the first potential which form the first conductor track.Type: GrantFiled: November 20, 2016Date of Patent: April 7, 2020Assignee: Semikron Elektronik GmbH & Co., KGInventors: Frank Stiegler, Stefan Schmitt, Harald Kobolla

Publication number: 20190375353Abstract: The invention relates to a battery unit for use on an electrical system of a motor vehicle, comprising a battery module and a coupling unit (30). The coupling unit has a first and a second connection (31 and 32), a first and a second DC converter (41 and 42). The first DC converter (41) allows a bidirectional current flow between the connections (31, 32), the second DC converter (42) allows a current flow from the first connection (31) to the second connection (32). The battery unit comprises a control system. The control system controls the DC converter. The invention also relates to a method for operating the battery unit on a motor vehicle's electrical system. A coupling current (1k) flowing through the coupling unit (30) is measured. When the coupling current (1k) flows from the first connection (31) to the second connection (32) and falls short of a first threshold value, the second DC converter (42) is connected and the first DC converter (41) is disabled.Type: ApplicationFiled: January 12, 2018Publication date: December 12, 2019Inventors: Manuel Hohenauer, Andreas Lemke, Bernd Heppner, Frank Stiegler, Henryk Weihs, Jens Koerner, Karl Kloess, Klaus-Juergen Schuler, Matthias Gernsbeck, Michael Steil, Steffen Adolf

Patent number: 7983250Abstract: A communications system for a motor vehicle, including a plurality of electrical components, a data bus structure to which the components are connected in order to transmit information among the components, and a power line structure to which the components are connected in order to be supplied with power. The information is transmitted in successive cycles over the data bus structure, each cycle including at least one time window for transmitting information at specific points in time and at least one event window for transmitting information in response to specific events. The communications system includes an arrangement for redundantly transmitting information which merely transmits the information transmitted in the at least one time window over the data bus structure at least partially over the power line structure as well.Type: GrantFiled: February 1, 2005Date of Patent: July 19, 2011Assignee: Robert Bosch GmbHInventors: Thorsten Enders, Thomas Fuehrer, Robert Hugel, Juergen Schirmer, Dieter Kraft, Frank Stiegler

Publication number: 20090237225Abstract: A supply line structure for the energy supply of electrical components of a motor vehicle, and for transmitting information between at least a portion of the components. To reduce the interference susceptibility of the supply line structure in a Powerline Communications, and at the same time to continue to be able to ensure the energy supply of the electrical components via the supply line structure, it is provided that the supply line structure have separate supply lines, electrically isolated from the vehicle body, as return lines from the components to at least one energy source of the motor vehicle. The supply lines of the supply line structure preferably take the form of coaxial lines or twisted pair lines.Type: ApplicationFiled: June 1, 2009Publication date: September 24, 2009Inventors: Thorsten Enders, Robert Hugel, Juergen Schirmer, Frank Stiegler, Klaus Dostert, Timo Kuhn

Patent number: 7583181Abstract: A supply line structure for supplying energy to electrical components of a motor vehicle, and for the transmission of information between at least a portion of the components (so-called Powerline Communications). To improve the channel characteristics of the information transmission via the supply line structure, it is proposed that the supply lines be arranged in a star configuration having at least one star point, the or each star point an impedance which corresponds to the characteristic impedance of the individual supply line branches running into it. To that end, it is proposed in particular that at the or each star point, an additional series resistor, frequency-dependent for frequencies below 100 MHz, be disposed in the incoming supply line branches. The series resistor is preferably configured as a ferrite sleeve.Type: GrantFiled: September 3, 2002Date of Patent: September 1, 2009Assignee: Robert Bosch GmbHInventors: Thorsten Enders, Juergen Schirmer, Frank Stiegler, Timo Kuehn, Klaus Dostert

Patent number: 7424326Abstract: A method and a computer program for modeling an interfering pulse in a vehicle electric system are described. Previous approaches for synthesizing such interfering pulses have proven to be insufficiently realistic for the simulation of certain application cases. An interfering pulse is therefore modeled by random determination of the parameters of the parameter set representing the interfering pulse to be modeled on the basis of the density functions belonging to the parameters and by substituting the parameters thus obtained into a predetermined mathematical function. The interfering pulse modeled in this way is also a suitable starting point for modeling a pulse pattern, i.e., a random sequence of individually spaced interfering pulses and a pulse interferer scenario, i.e., a random sequence of individually spaced pulse patterns.Type: GrantFiled: September 2, 2004Date of Patent: September 9, 2008Assignee: Robert Bosch GmbHInventors: Thorsten Enders, Frank Stiegler, Klaus Dostert, Thorsten Huck
