摘要
文章提出了一种基于重复控制与电压双闭环控制相结合的单极倍频SPWM正弦波逆变器控制方案,详尽阐明了单极倍频SPWM控制方式的工作原理,并给出了逆变系统的数学模型,在此基础之上研究了重复控制与电压双闭环控制相结合的控制方案。实验结果表明:这种逆变器输出电压只有较小的谐波含量,同时具有良好的动态特性。
A kind of control scheme incorporating repetitive control and voltage feedback dual closed-loop control is proposed for diploid SPWM inverter. The paper introduces a method of diploid SPWM. Mathematical mold of the inverter is given out. At last, the paper puts forward a controlled method based on repetitive control and voltage feedback dual closed-loop control. Experiment verified that this inverter has low THD and quick dynamic characteristic.
