    Abstract: Certain embodiments of the present invention relates to a method for controlling operation of a parallel converter system. The parallel converter system includes multiple parallel power converters, and each of the parallel power converters is coupleable to a corresponding controller. The method includes: generating, via each of the controllers, a channel reference signal, transmitting each of the generated channel reference signals to a corresponding one of the parallel power converters, and adjusting an output current of each of the parallel converters responsive to the corresponding channel reference signals received, the adjusting controlling a combined output current of the parallel converter system. The channel reference signals of these parallel power converters are generated in response to the participation factors of each of the parallel power converters, and a net converter output reference current.

    Abstract: A stator for an electrical machine (e.g., a motor or generator) is described. The stator includes a stator core consisting of a plurality of axially adjacent generally annular laminations. The stator has axially extending stator teeth between adjacent pairs of which are formed axially extending stator slots for receiving conductors of a stator winding. At least one of the stator teeth includes an axially extending cooling passageway through which a cooling fluid flows in use. The electrical machine can include means for circulating cooling fluid through the cooling passageway(s) to cool the stacked laminations and means for circulating air around the stator along an air cooling circuit where the circulated air is cooled by the stator laminations and there is no need for a separate heat exchanger.
