Energy converter for galvanically coupling a first DC link to a second DC link

摘要

The invention relates to an energy converter (10) for galvanically coupling a first DC link (12) to a second DC link (14), the first DC link (12) having a first DC link voltage (16) and the second DC link (14) having a second DC link voltage (18), the first and second DC voltage intermediate circuit (12, 14) using a common electrical reference potential (22). The energy converter has a first switching element (30) for electrically separating the shared reference potential (22) between the first and the second DC voltage intermediate circuit (12, 14) and a second switching element (32) for coupling a first operating potential (20) of the first DC voltage intermediate circuit (12) to a second operating potential (24) of the second DC voltage intermediate circuit (14).
