A power supply system has an n-phase electric machine, where n≧1, and a controllable energy store serving to control and to supply electrical energy to the electric machine. The controllable energy store has n parallel power supply arms which each have at least two series-connected energy storage modules which each include at least one electrical energy storage cell with an associated controllable coupling unit, are connected on one side to a reference bus and are connected on the other side to one respective phase of the electric machine. In dependence on control signals, the coupling units either bridge the respectively associated energy storage cells or connect the respectively associated energy storage cells into the power supply arm.
