Abstract: A method and related apparatus for extending a DC voltage range of a rectifier circuit for the supply, from an AC grid, of a DC load which is connected to a DC rectifier output of the rectifier circuit, wherein an AC rectifier input of the rectifier circuit is connected via a grid connection point to the AC grid, wherein the rectifier circuit includes an AC/DC converter having an AC input and a DC output, wherein the AC/DC converter includes a converter circuit having semiconductor switches and freewheeling diodes connected in an antiparallel arrangement thereto, wherein an inductance is connected between the AC input of the AC/DC converter and the grid connection point. The method includes setting a desired DC operating voltage UDOC,soll on the DC output of the AC/DC converter or on the DC rectifier output, or both, by an actuation of semiconductor switches of the AC/DC converter, wherein, when the desired DC operating voltage UDC,soll lies below a value of an amplitude Û4 of an alternating voltage on the AC input of the AC/DC converter, the semiconductor switches of the AC/DC converter are actuated for an exchange of reactive power Q1(t) with the AC grid, which has a voltage-lowering effect upon the amplitude Û4 of the AC voltage at the AC input of the AC/DC converter, such that the amplitude Û4 approaches the desired DC operating voltage UDC,soll, and wherein the exchange of the reactive power Q1(t) with the AC grid is executed during or shortly before an electrical connection or an electrical isolation of the DC load to or from the rectifier circuit.

Abstract: An inverter has an inverter bridge connected between two DC busbars on the input side and connected to an AC output on the output side. The two DC busbars run, in a manner overlapping one another, in planes which are parallel to one another. The inverter bridge has a subcircuit having a plurality of semiconductor switches between the AC output and each DC busbar. Semiconductor modules which form the two subcircuits are connected, in a manner arranged beside one another, to the two DC busbars and to the AC output via connections. A connection element which leads to the AC output begins on that side of the DC busbar which faces the semiconductor modules in a region overlapped by the DC busbars and connects the semiconductor modules of the two subcircuits to one another there.

Abstract: The method of detecting an arc fault in a power circuit includes determining a first signal related to current flowing in the power circuit is determined and analyzing the first signal to determine whether the signal indicates the presence of an electric arc in the power circuit. In case the first signal indicates the presence of an electric arc in the power circuit, means for suppressing an electric arc are activated. A second signal related to current flowing in the power circuit is then determined and analyzed. An occurrence of an arc fault in the power circuit is signaled if the second signal does not indicate the presence of an electric arc. The system for detecting an arc fault is designed to perform a corresponding method.
