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 drive circuit including a first transformer unit in connection with a pulse amplifier module and a second transformer unit in connection with a plurality of power semiconductor groups, each group containing one or more power devices. The first transformer unit includes at least one primary transformer configured to receive a current pulse at a primary winding from a current pulse generation module, the current pulse being reflected to a secondary winding. The second transformer unit includes a plurality of secondary transformers where each secondary transformer is configured to receive the current pulse at a primary winding thereof, the current pulse being reflected to a secondary winding coupled to a pulse receiver module. The first and second transformer units reduce parasitic coupling between the pulse receiver module and the control module.
