The invention relates to a circuit arrangement (1) for operating an electric machine (2, 2a), which has a plurality of lines (U, V, W), each for one phase of an alternating current to the electric machine, each line (U, V, W) having a plurality of series-connected switching elements (10, 11) that form a half bridge (12), the half bridge (12) having a terminal (13) between two switching elements (10, 11), and the circuit arrangement (1) being electrically couplable to the electric machine (2, 2a) via the terminals (13) of the half bridge (12). The circuit arrangement is characterised in that each line has a plurality of half bridges (12), which are electrically connected parallel to each other.
