Patent number: 11626727Abstract: An energy supply network has a bus line with a line impedance for energy distribution. The energy supply network also includes a number of power-electronic converters having a respective commutation capacitor wherein the storage capacity thereof is selected in such a way that a controlling of the associated power-electronic converter is guaranteed during operation of the energy supply network and an excess of voltage is managed during a commutation. At least one energy accumulator is provided, which can be connected selectively to the bus line by controlling a switch device via a computer unit, wherein the storage capacity of the energy accumulator is substantially greater than the storage capacity of a respective commutation capacitor.Type: GrantFiled: February 12, 2020Date of Patent: April 11, 2023Assignee: Siemens Energy Global GmbH & Co. KGInventors: Karsten Handt, Sebastian Nielebock, Markus Pfeifer, Jens Weidauer

Patent number: 11223287Abstract: A resonant DC-DC converter includes an inverter circuit, a rectifier circuit and a transformer unit. The inverter circuit is connected to a first terminal of the transformer unit, and the rectifier circuit is connected to a second terminal of the transformer unit. The first and second terminals are galvanically isolated from one another by a first transformer. The transformer unit is configured to adapt a transformation ratio of the transformer unit. The transformer unit has an energy transmission path which includes an inverter and a second transformer, with an input of the energy transmission path being arranged parallel to a primary side of the first transformer and an output of the energy transmission path being arranged in series with the secondary side of the first transformer.Type: GrantFiled: August 22, 2018Date of Patent: January 11, 2022Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Martin Hergt, Marcel Lutze, Sebastian Nielebock, Markus Pfeifer, Markus Zocher

Patent number: 10177682Abstract: The present disclosure relates to converter modules. The teachings thereof may be embodied in converter modules for a multi-level energy converter. For example, a method for operating a converter module of a multi-level energy converter by means of a control unit and via a control connection may include: controlling the switching states of one of two converter module connections of the converter module and a switching unit incorporating the control connection. Two series-connected converter module capacitors connected to the switching unit respectively deliver a converter module capacitor voltage. The switching unit switches the converter module capacitor voltage of one of the converter module capacitors or a summed voltage of the series-connected converter module capacitors to the converter module connections, according to the respective switching state of the switching unit.Type: GrantFiled: February 22, 2016Date of Patent: January 8, 2019Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Gopal Mondal, Matthias Neumeister, Sebastian Nielebock
