In order to enhance the ability of harmonic suppression for multi-pulse converters (MPCs). This paper proposes a novel pulse multiplication method at DC side of MPCs. The presented rectifier consists of a three-phase bridge parallel structure 12-pulse rectifier and a novel double winding tapped inter-phase converter (TIPC). The functions and characteristics of delta-connected autotransformer and ZSBT are introduced, and the working modes of TIPC are analyzed in detail. Simulation results show the correctness and effectiveness of the proposed method. The results show that the TIPC is simpler than the tapped inter-phase reactor (TIPR) in the aspect of control, and the switching device of TIPC has lower conduction loss. The results show that the proposed method is of practical significance to improve the application level of MPC in high power occasions. In contrast, the proposed rectifier is more efficient in high power situations.
