Abstract
A power supply system for a long-stator drive, whose stator winding along a path for a magnetic levitation train is subdivided into several controllable stator segments. The stator segments are controllable via at least one segment switch on at least one section cable system running along the stator segments. At least one frequency transformer is provided per section cable system, with the frequency transformer(s) arranged in at least one substation along the stator segments. Each frequency transformer generates a supply voltage system for the stator segments, with the nominal voltage in the section cable system being greater than the nominal voltage of the stator segments. At least one matching transformer is connected between the section cable systems and the stator segments, through which the nominal voltage of the section cable system can be transformed down to the nominal voltage of the stator segments.
