Abstract
A circuit assembly for linking different electrical voltage levels in a motor vehicle, comprising: an electric machine containing induction coils in a star circuit connection with a star point; a first switch unit containing switch elements for generating an AC voltage for the electric machine from a DC voltage of a first voltage level; a DC voltage of a second voltage level; and a second switch unit for a bidirectional electrical energy flow between the DC voltage of the first voltage level and the DC voltage of the second voltage level, wherein the second switch unit has two switch elements arranged in series in an auxiliary switch branch, wherein the auxiliary switch branch is connected in parallel to the DC voltage of the first voltage level, and each connection of the switch elements is connected to the star point.
