摘要： An exemplary converter arrangement and method in connection with the arrangement includes a converter arranged in a closed container or similar structure. The container has a high voltage compartment and a low voltage compartment. The high voltage compartment includes a transformer connectable to a network to be supplied and the low voltage compartment includes the converter. The arrangement being configured to exchange heat from the high voltage compartment to the low voltage compartment and heating the low voltage compartment with losses of the transformer.

摘要： A solar power plant is disclosed for converting solar energy into electric energy, and having a plurality of solar cell units, each solar cell unit containing a first cell pole and a second cell pole. The cell poles can cooperate for feeding electric energy produced by the solar cell unit as direct current out of the solar cell unit. A direct-current converter can include a plurality of direct-current input poles and two direct-current output poles, each direct-current input pole being connected to at least one cell pole. The direct-current converter can convert input direct currents entered via the direct-current input poles, and having input voltages, into an output direct current having an output voltage, and feed the output direct current via the direct-current output poles out of the direct-current converter. The direct-current converter can include a three-phase inverter unit having three phase poles and two direct-voltage poles, the inverter unit being adapted to serve as a direct-current converter in such a manner that each of the three phase poles are adapted as direct-current input poles and each of the direct-voltage poles is in electrically conductive connection to exactly one direct-current output pole of the direct-current converter.
