A primary unit is provided for producing an electromagnetic charging field for inductive coupling to a secondary coil. The primary unit has a multi-part primary coil, which includes N coil sections, with N>2, which are coupled to each other on a first end in the shape of a star. Moreover, the primary unit has N half-bridges, which are each coupled to a second end of the N coil sections. In addition, the primary unit has a control unit, which is configured to control the N half-bridges in relation to the secondary coil.
