Abstract
This paper presents a general control approach to achieve power-factor correction (PFC) for three-phase boost rectifiers with center-tapped or split DC output capacitors. These rectifiers can be decoupled into a series-connected dual-boost topology during each 60/spl deg/ of line cycle. A new extension of the constant-frequency one-cycle control strategy is proposed to provide the core PFC function for the dual-boost topologies. The additional logic circuits rotate the PFC functions in three phase. No multiplier is necessary to scale the current reference as required by many other approaches. Hence, this control approach is simple and general. Furthermore, the constant switching-frequency modulation is desirable for electromagnetic interference filter design and switching losses are minimized since only two high-frequency switches are controlled at any time. Simulation and experimental results are presented to verify the theoretical analysis.Keywords
