Abstract: A method and device for controlling the n LLM coils of an LLM stator making it possible to change the polarity of the coil voltage of the n LLM coils more easily and with little circuit complexity. It is proposed to apply a first operating potential to n first input terminals of n half bridges, and apply a second operating potential to n second input terminals of the n half bridges. For each half bridge, a first switch is connected between a center point of the respective half bridge and the first input terminal, and a second switch is connected between the center point of the relevant half bridge and the second input terminal. The center point of the n half bridges is connected in each case to n first terminals of then LLM coils, and the second terminals of then LLM coils are connected in a control point that is regulated to a predetermined potential.
