Abstract: This paper contains the evaluation and comparison between DPC methods for two-level (2-L) and three-level (3-L) AC/DC converters, in order to demonstrate de great advantages of using a three level rectifier type NPC. The theoretical principal of this methods as well as the synthesis of the active and reactive power are discussed. The regulation of DC-bus voltage is achieved using PI controller. The effectiveness of this approach is shown by simulation results using Power System Bloc set (PSB) of Matlab/Simulink.
