Modular electric power generating system with multistage axial flux generator

An electrical power system comprising:

• a direct current (DC) bus connected to a load;
• a plurality of generators driven by rotation of a common shaft;
• a plurality of power converters, each comprising an active rectifier controller that operates a respective associated one of a plurality of active rectifiers to rectify multi-phase alternating current (AC) from a respective associated one of the plurality of generators to DC on the DC bus;
• and
• a load sharing controller operable to provide a respective corrective signal to each respective power converter that is enabled, the respective corrective signals based on a difference between an average output current across all of the active rectifiers that are enabled, and a particular output current of the respective power converter;
• wherein each active rectifier controller is operable to determine a quadrature current value for the generator associated with the active rectifier controller based on the corrective signal provided to the power converter of the active rectifier controller, and control the active rectifier associated with the active rectifier controller based on the quadrature current value.
