The invention discloses an inverter (10) for converting an input-end direct current into an output-end alternating current to be fed into an AC voltage supply system. The inverter (10) comprises a first housing part (11) with direct-current connections (15) for receiving direct-current lines of a direct-current generator, a second housing part (12) with alternating-current connections (16) for receiving alternating-current lines of an AC voltage supply system, a third housing part (13) for receiving power-electronics components of a DC voltage converter, and also a fourth housing part (14) for receiving power-electronics components of an inverter bridge circuit. The housing parts (11-14) each have a substantially planar rear wall and are arranged in such a way that they surround a cooling-air duct (17) with a substantially rectangular cross section, wherein the first housing part (11) is arranged opposite the second housing part (12), and the third housing part (13) is arranged opposite the fourth housing part (14). A heat sink (18) is arranged in the cooling-air duct (17) and has two opposite and substantially planar cooling surfaces (19a, 19b), wherein the cooling surfaces (19a, 19b) are associated with the rear walls of the third housing part (13) and of the fourth housing part (14) and are in thermal contact with power-electronics components which are arranged in said housing parts (13, 14). |
