Patent ID: 7928623

Claim:
An apparatus for producing electrical power from mechanical power, comprising: a generator with a rotor and a stator for conversion of mechanical power to a polyphase alternating current having more than three phases, wherein the generator is connectable to an electrical grid for providing power to the electrical grid; the stator having a plurality of parallel stator slots a plurality of stator winding bars being disposed in the stator slots, and being connected in series so as to form a polygonal generator for producing the polyphase alternating current; and a static frequency converter in the form of a matrix converter for conversion of the polyphase alternating current to a desired output alternating current, wherein the stator is a polygonal stator, wherein inputs to the matrix converter are connected to end connections of the winding bars, and wherein for k stator slots and for a polyphase alternating current with m phases, every k/m-th end connection of the winding bars is connected, forming one phase of the polyphase stator alternating current.
