摘　　要：针对传统三电平空间电压矢量存在的区间划分繁琐、矢量作用时间计算复杂等问题,同时为消除中点电位漂移的影响,设计了一种引入冗余零矢量修正的等效载波层叠空间矢量调制(SVM)方式。为抑制网侧电压谐波并进一步改善网侧电流质量,设计采用了比例与重复并联的电流内环复合控制策略,给出了详细的理论分析与控制系统设计方案。构建了完整的系统仿真模型与实验样机,仿真与实验结果表明,所提的控制策略有效改善了网侧电流波形质量,系统动静态性能良好,实现了单位功率因数整流。The traditional throe-level space vector modulation （SVM） requires a large calculation of partitioning and voltage vector,at the same time to eliminate the influence of neutral voltage imbalance.A new kind modulation named carrier-based with zero sequence components correction is designed.In order to eliminate the influence by voltage harmonics and improve the current quality, the compound control strategy named proportional and repetitive controls in the current loop is put forward.The detailed theoretical and control system are analyzed.In order to test and verify the effectiveness of the proposed control method, the completely simulation and experimental prototype platform are built, simulation and experimental results show that the quality of grid current is improved, the dynamic performance is good and unit power factor correction is realized.
