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.
