| 摘 要： | 当多重叠架式逆变器重数过多时系统结构庞大，驱动脉冲的分配也比较复杂，提出一种新型差补逆变器的拓扑结构及PWM的控制方法，利用差补技术在逆变器层数不变的情况下可得到更多的电平，从而改善逆变器的性能，实验结果证实了分析的正确性。

| Abstract: | When the number of multi-overlaped units increases, cascaded inverter will become complicate and difficult to assign drive signal. This paper proposes a novel differential PWM technology, which is expected to play a greater role in cascade inverter. By applying differential PWM, more PWM level can be obtained while cascaded number keep same. So it improved the performance of inverter. The correctness of analysis is verified by experiment. |
