Abstract

See full text

The invention relates to an electrical energy conversion system (11) which is particularly suited for use in wind energy conversion systems. The system includes two magnetically separated permanent magnet machines (25, 27) linked by a freely rotating rotor (19) housing permanent magnets (39). The first machine is typically a synchronous generator, and the second an induction generator. The synchronous generator (25) has a stationary stator (21) which is connectable to an electrical system such as an electricity grid, and the induction generator (27) has a rotor (17) which is connectable to a mechanical drive system such as, for example, a wind turbine.
