摘要：

The mathematical model and working modes of the three-phase two-arm three-level neutral-point-clamped (NPC) pulse width modulation (PWM) rectifier were analyzed, and a novel dual single-input single-output (SISO) model based on α-β stationary reference frame was proposed, in which the α-axis and β-axis equivalent model are shown to be similar to two traditional single-phase boost converters. Switching strategies were analyzed to determine switching control signals in a switching period based on space vector modulation. The model makes it much easier to analyze a complex three-phase three-level PWM rectifier and to implement by the digital signal processor (DSP). The simulation and experimental results verify the validity of the three-phase two-arm three-level PWM rectifier and the dual SISO control strategy. © 2009 Chin. Soc. for Elec. Eng.
