为降低Vienna整流器的生产成本,提高控制算法的工作效率,设计了基于无电流传感器的单闭环控制策略.针对Vienna整流器的中点电位波动和传统三电平空间矢量调制(SVPWM)计算繁琐的问题,引入一种基于载波调制的简化等效SVPWM技术,主要是通过在零序分量中加入平衡因子来控制中点电位平衡.单闭环控制算法和等效SVP-WM相结合大大简化了控制系统的设计过程,提高了整个控制系统的工作效率.最后通过实验验证了该控制算法的正确性和高效性.

In order to reduce the cost of three-phase Vienna-type rectifiers and improve the efficiency of corre-sponding control algorithms, a single closed-loop strategy without current sensor is designed.Aiming at the prob-lems of the neutral point voltage unbalance and the complex calculation of the space vector pulse width modulation ( SVPWM) topology of Vienna-type rectifiers, a simplified equivalent SVPWM technology is proposed based on carrier modulation, which controls the neutral-point potential balance mainly by adding the balance factor into the zero-sequence component.The combination of the single closed-loop control algorithm with the equivalent SVPWM simplifies the design process of the control system, and improves the efficiency of the whole control system.Final-ly, the correctness and effectiveness of the proposed algorithm are verified by an experiment.
