摘要:
VIENNA整流器因其输出侧上下电容参数特性不一致、控制方法运用不适合,导致出现中点电压不平衡,不利于整流器的安全稳定运行。针对这个问题,研究VIENNA整流器工作时各矢量对中点电位的影响,并设计一种中点电位波动小的高性能整流器。为了简化控制过程,将目标矢量旋转到第一个大扇区,然后将三电平空间矢量平面转移为两电平空间矢量平面,然后进行SVPWM调制,仿真结果验证了方法的可行性,可以在VIENNA整流器运行时有效压制中点电位。
Abstract:
Due to its inconsistent upper and lower capacitance parameters on the output side of the VIENNA rectifier, the control strategy is not suitable, resulting in the mid-point voltage imbalance and not conducive to the safe and stable operation of the rectifier. Therefore, the influence of each vector on neutral voltage, when the VIENNA rectifier is at work, is studied, and a kind of neutral voltage fluctuations small high-performance rectifier is designed. In order to simplify the control process, the target vector is rotated to the first big sectors, and the three-level space vector plane is transferred into two-level space vector plane. Then, the SVPWM modulation is carried out. The simulation results verify the feasibility of the method which can effectively suppress the midpoint potential in VIENNA rectifier runtime.
