Abstract
In one embodiment, the present invention includes a turbine to generate mechanical energy from kinetic energy, a generator coupled to the turbine to receive the mechanical energy and to output multiple isolated supply powers, and multiple power stages each coupled to the generator. Each of the power stages may receive at least one of the isolated supply powers.
Claims20
A system comprising:
- a turbine to generate mechanical energy from kinetic energy;
- a generator coupled to the turbine to receive the mechanical energy and to output a plurality of isolated supply powers;
- and
- a plurality of power stages each coupled to the generator, wherein each of the plurality of power stages is to receive at least one of the isolated supply powers, and a first subset of the power stages are coupled to a first phase output line and a second subset of the power stages are coupled to a second phase output line.

An apparatus comprising:
- a generator to receive mechanical energy from a turbine to provide a plurality of isolated power outputs directly to power stages of a power converter, wherein the generator includes a rotor and a stator, the stator having a plurality of slots each having at least one coil wrapped there around, wherein the generator is to provide up to S isolated power outputs, wherein S is at least equal to P·n, where P is the number of phase output lines of the power converter and n is the number of power stages coupled in series to one phase output line.
A system comprising:
- a plurality of wind turbines each coupled to at least one generator to output mechanical energy to the at least one generator;
- the plurality of generators each coupled to one of the wind turbines to receive the mechanical energy and to output a plurality of isolated supply powers;
- and
- a power converter connected to the plurality of generators, the power converter including a plurality of power stages each to receive at least one of the isolated supply powers, wherein a first subset of the power stages are coupled to a first phase output line and a second subset of the power stages are coupled to a second phase output line.
