大功率PWM电流源电机驱动系统中基于直流母线虚拟阻抗的谐波交互抑制方法详细分析

For high-power PWM current-source motor drive systems, due to the low converter switching frequency and the relative small dc choke for reduced cost/weight, the converters' switching harmonics may interact through dc link and produce interharmonics in the entire system. Such harmonics interaction phenomenon may give rise to the system resonance at certain motor speeds, which degrades the grid-side...
