【摘要】 针对级联型多电平逆变器,提出了一种高性能的空间矢量控制方法。这种方法基于空间矢量理论确定与参考电压矢量误差最小的电压矢量,它能够在接近基频的开关频率下输出接近正弦波的电压。仿真结果证实了空间矢量控制所具有的一系列显著优点。更多还原

【Abstract】 This paper presents a high-performance space vector control(SVC) strategy for cascaded multilevel inverter.The proposed strategy generates a voltage vector across the load with minimum error with respect to the sinusoidal reference based on the space vector theory.In addition,it generates almost sinusoidal voltages with nearly fundamental switching frequency.Simulation results proved the advantages of SVC technique.更多还原
