摘　　要：在高电压领域,有源中点箝位型五电平(ANPC-5L)整流器比三电平更具优势。对大功率ANPC-5L PWM整流器主电路拓扑进行分析,提出一种适用于该拓扑结构的五电平空间矢量脉宽调制(SVPWM)控制算法。通过建立五电平整流器数学模型,为整流器系统的设计奠定了理论基础;根据瞬时功率理论,计算出系统所需的有功、无功功率,并采用SVPWM控制方法实现了ANPC-5L的定频控制、高动态性能及单位功率因数控制;最后,通过实验验证了所提SVPWM控制策略及该定频直接功率控制(DPC)方法的正确性和有效性。In the field of high voltage,active neutral point clamped five-level（ANPC-5L） rectifier has more advantages than three-level.Based on the high power considerations,the ANPC-5L PWM rectifier is analyzed,a space vector pulse width modulation（SVPWM） control algorithm is proposed for the new topological structure.The mathematical model lays the theoretical foundations for five-level rectifier, then according to the instantaneous power theory to calculate the active and reactive powers.In addition, the constant frequency control ,high dynamic performance and unit power factor control are realized according to the SVPWM control method.Finally,the correctness and validity of the SVPWM control algorithm and the fixed frequency direct power control（DPC ） method are verified by the experiment.
