Abstract

The invention relates to a system comprising an n-phase electric machine (1), which can be controlled with the aid of a controllable first energy store (2) and is supplied with electric power. Said controllable energy store (2) comprises n parallel power supply branches (3-1, 3-2, 3-3) which can be connected to a reference bus (T-) and to one respective phase (U, V, W) of the electric machine (1). An intermediate circuit (10) can be coupled to a neutral point (S) of the electric machine (1) and to the reference bus (T-). According to an operational method, the supply of power from electric consumers (12;13) connected directly or indirectly to the intermediate circuit (10) is carried out by increasing or decreasing the voltages on the power supply branches (3-1, 3-2, 3-3) respectively to a value higher or lower than an actual voltage value required for supplying power to the electric machine (1).
