Patent number: 9214873Abstract: A method for operating an electrical power rectifier. The power rectifier comprises at least two branches that are connected in parallel to each other, each of the branches comprising at least two power semiconductor elements that are connected in series. The collector-emitter voltage Vce(t) and/or the collector current Ic(t) of one of the power semiconductor elements is detected by means of the method. Furthermore, it is determined whether at least one of the following conditions is met: dVce(t)/dt<(dVce/dt)crit, and/or dIc(t)/dt<(dIc/dt)crit, and or Ic(t_ent)<Iccrit. If at least one of the aforementioned conditions has been met, the gate-emitter voltage of at least one of the power semiconductor elements is increased.Type: GrantFiled: December 18, 2013Date of Patent: December 15, 2015Assignee: GE Energy Power Conversion GmbHInventors: Roland Jakob, Piotr Sadowski, Thomas Bruckner, Thomas Basler

Publication number: 20140325102Abstract: A method for operating a slave node of a digital bus system is described. The slave node comprises two sending and receiving devices. In the bus system, an input data frame is sent to a master node in input direction. The slave node receives the input data frame by the first sending and receiving device. The slave node stores service data packets contained in the input data frame in a FIFO memory. The slave node attaches at least one process data packet of its own to a last process data packet in the input data frame. The slave node attaches the service data packets to the process data packet, which is now last, in the input data frame. The slave node sends the input data frame, which was changed in this manner, to the next node in input direction by the second sending and receiving device.Type: ApplicationFiled: April 29, 2014Publication date: October 30, 2014Applicant: GE Energy Power Conversion GmbHInventors: Thorsten OPITZ, Frank WOTHE
