摘要： A device for converting direct voltage from a store, particularly from an electrochemical store (2), or a fuel cell, to alternating voltage, in particular for feeding into a supply network, is characterized by a two-stage design having a single DC/DC converter stage (3, 22) for generating an intermediate circuit voltage from the output voltage of the store or the fuel cell, which converter stage is designed and can be actuated such that it converts, in particular raises, the direct voltage in a wide input voltage range directly to an intermediate circuit voltage with which the DC/AC converter stage can be operated to generate the alternating voltage, wherein the DC/DC converter unit is designed to be electrically isolating and has a high-frequency transformer, and a single DC/AC converter stage for generating the alternating voltage from the intermediate circuit voltage. The invention further relates to a method for actuating a device for converting direct voltage from a store or energy generator, particularly from an electrochemical store (2) or a fuel cell, into alternating voltage for feeding into a supply network.
