| 摘 要： | 针对H桥级联型多电平逆变器,对比分析了传统的多电平PWM调制策略,指出其存在的输出电压谐波性能问题。提出一种改进的调制策略,不仅抑制了直流母线电压波动引起的低次谐波含量,而且有效地降低了高、次谐波含量。最后通过对比实验,验证了所提出方法的正确性与有效性。

| Abstract: | Traditional multilevel PWM modulation strategies are analysed for cascaded H-Bridge multilevel inverter,and the problem of output voltage harmonic performance is pointed out.Then,a novel modified modulation strategy is proposed,it not only suppresses the lower-order harmonics caused by dc-link ripples,but also lowers down the high-order harmonics.Finally,the validity of the proposed method is verified by contrastive experiments. |
