A printed circuit board () 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 () and one conductive DC&#x2212; layer () for each conductive DC+ layer (), for conducting the input phase. There is at least one high-side power semiconductor () for each output phase (U, V, W) and one low-side power semiconductor () for each high-side power semiconductor (), for switching the input phase. The at least one DC+ layer () corresponding to a respective DC&#x2212; layer () is formed in a cover surface area (), which covers at least 75% of the input phase surface area.
