SUPPLY DEVICE FOR SUPPLYING ELECTRICAL CURRENT TO AN ELECTRICAL GRID AND METHOD FOR OPERATING A SUPPLY DEVICE OF THIS TYPE

摘要

The invention relates to a supply device (10) for supplying electrical current provided by at least one current source (14) to an electrical grid (12), said device comprising at least one current converter (16) that can be electrically coupled to the current source (14) and at least one connection device (20) which is electrically coupled to an electrical line (24) via an input connection and electrically coupled to the current converter (16) via said line. The connection device is designed to be electrically coupled on the output side to the electrical grid (12) and to adapt an electrical voltage at the input connection to an electrical voltage of the electrical grid (12) at the output side.
