 Abstract: The magnetic confinement of the plasma in WENDELSTEIN 7-X (W7-X) will be determined by 50 superconducting non-planar coils and 20 superconducting planar coils. The coils are grouped in five periodic modules with ten coils each connected in series. In order to be able to vary the magnetic configuration and hence increase the experimental flexibility the five groups of non-planar coils and two groups of planar coils will be powered individually resulting in seven independent power supplies. To fine tune the magnetic configuration, shift the plasma axis and to modify the plasma edge an additional set of ten normal conducting control coils will be mounted. Other aims are to correct small field errors and to distribute the heating power on the target plates over a wider range. In order to correct field errors a direct current is necessary, whereas an alternating current is essential for the second aim. The paper describes the design of the two types of power supplies for W7-X as well as the results of the first tests of components.
