Electrical Power Systems and Subsystems

An electrical power subsystem for connection to a power grid, the electrical power subsystem comprising:

• a generator comprising a generator stator and a generator rotor;
• a power converter electrically coupled to the generator, the power converter comprising:
• a plurality of rotor-side converters electrically coupled in parallel;
• a line-side converter;
• and
• a regulated DC link electrically coupling the plurality of rotor-side converters and the line-side converter;
• a stator power path for providing power from the generator stator to the power grid;
• a converter power path for providing power from the generator rotor through the power converter to the power grid;
• a transformer connecting the subsystem to the power grid;
• and
• a controller coupled to the power converter, the controller configured to coordinate switching of the plurality of rotor-side converters to produce an interleaved switching pattern between the plurality of rotor-side converters.
