Abstract

An example electrical power system includes a DC bus connected to a load, a plurality of generators driven by rotation of a common shaft, and a plurality of power converters. Each power converter includes an active rectifier controller that operates a respective active rectifier to rectify AC from a respective one of the generators to DC on the DC bus. A load sharing controller is operable to provide a respective adjustment signal to each respective power converter that is enabled, the respective adjustment 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. Each active rectifier controller is operable to determine a quadrature current value for its associated generator based on its adjustment signal.
