The invention relates to a method for operating a converter in an energy distribution system, wherein, by means of the converter, an electrical energy provided by a source is fed into an AC electricity network at a coupling point (E) or electrical energy is drawn from the AC electricity network at the coupling point (E), wherein the AC electricity network is coupled to further converters for feeding in or drawing electrical energy, wherein the converter has an inverter provided with power switches in order to provide an electrical variable, comprising providing one or a plurality of system state variables indicating a system state of the electricity network, selecting one of a plurality of commutation patterns depending on the one or the plurality of system state variables, and driving the inverter according to the selected commutation pattern.

Method and apparatus for operating a converter in a converter-based power distribution system, and power distribution system having a plurality of converter-based power transmission units

A power-electronic arrangement comprising semiconductor components (), a heat exchanger (), and an electrically conductive element () is presented. The heat exchanger comprises evaporator channels () and condenser channels () for working fluid. The electrically conductive element comprises a contact surface providing a thermal contact to outer surfaces of walls of the evaporator channels for transferring heat from the electrically conductive element to the evaporator channels. A main current terminal of each semiconductor component is bonded to the electrically conductive element which thus forms a part of a main current circuitry of a power system. As the main current terminal is directly bonded to the electrically conductive element cooled with the heat exchanger, the temperature gradients inside the semiconductor components can be kept moderate, and thus the temperatures inside the semiconductor components can be limited.

Power-electronic arrangement

A mechanical construction of an electrical module includes two or more electrical components (-). Each of the electrical components has a contact surface (-) that is capable of forming a galvanic contact with an external electrical conductor. The electrical module includes a holder element () that includes flexible material arranged to flexibly support the electrical components with respect to each other in such a way that the contact surfaces of the electrical components are capable of aligning with external surfaces independently of each other.
