Abstract：The three-phase voltage mode PWM rectifier is widely used in the production for reducing the input current harmonic content and improving the power factor of system. In some 3P4W connection occasion, the three-phase four legs rectifier is one of the 3P4W (three-phase four-wire) topologies. The one-cycle control (OCC) strategy used in the PFC circuit is widely researched because of simple circuit and needless of the multiplier and sampling input voltage. The OCC which used in the different topologies is also a important research direction. The OCC theory used in three-phase four-leg rectifier was analyzed in the paper, the different operation modes and input current characteristic of rectifier which controlled by traditional single-edge modulation was discussed. The relation between DC component exists in the input current and switch frequency and input inductor was revealed. Based on the analysis, the symmetry bi-edge modulation was proposed, the DC component in the input current can be restrained by the proposed method. System simulation and experimental results verified the theoretical analysis.
