摘要： A printed circuit board (1) comprises a conductive outer layer (2) and at least one conductive inner layer (4, 14). At least one bus bar (7, 8) for conducting high current and at least one power semiconductor (12) for controlling and/or activating the high current are disposed on a side of the outer layer (2) facing away from the at least one inner layer (4, 14). The printed circuit board (1) allows for a high level of component density while simultaneously providing for effective heat dissipation. Furthermore, the printed circuit board (1) can be produced economically and flexibly.

摘要： A printed circuit board (1) for converting an input phase to at least one output phase (U,V,W), which has an input phase surface area with at least one conductive DC+ layer (28) and one conductive DC− layer (29) for each conductive DC+ layer (28), for conducting the input phase. There is at least one high-side power semiconductor (6) for each output phase (U, V, W) and one low-side power semiconductor (7) for each high-side power semiconductor (6), for switching the input phase. The at least one DC+ layer (28) corresponding to a respective DC− layer (29) is formed in a cover surface area (2), which covers at least 75% of the input phase surface area.
