Abstract

The proposed GTO converter system has the better harmonic characteristics, especially, in the distortion factor (55%), than the conventional 12-step converter system. The improved harmonic characteristics was achieved through the unsymmetrical angle control of the each converter. In addition, the proposed system can save the cost (20%), spase (50%) and weigh (8%). The proposed system was studied in simulation and experiment.
