The present disclosure discloses a method and an apparatus for implementing the method for producing a three-phase current to a three-phase output. The method comprises producing a positive current, a negative current, and an intermediate current by using switching converters. The produced positive current follows a path of a highest phase of a sinusoidal three-phase signal at a given time, the produced negative current follows a path of a lowest phase of the three-phase signal at the given time, and the produced intermediate current follows a path of a phase of the three-phase signal between the highest and the lowest phase at the given time. The produced currents are switched to each phase conductor of the three-phase output in sequence so that phase currents of the three-phase current are formed in the output conductors. |
