In this paper, the common-mode voltage (CMV) of VIENNA rectifier is analyzed, and a new modulation method using only zero CMV (ZCMV) vector is proposed. The voltage fluctuation of the neutral point is suppressed by introducing a flying-capacitive (FC) leg. The simulation results show that the amplitude of CMV is reduced by more than 90% and the common-mode conducted electromagnetic interference (EMI) is reduced by 30dB compared with conventional modulation. With the control of the FC leg, the amplitude of the voltage fluctuation at the neutral point is reduced significantly. This novel topology can be applied in three-phase AC-DC power conversion which considers EMI and power quality.
