| 摘 要： | 为了对单相三电平逆变器的输出电压进行调节,在多载波层叠调制策略的基础上,引入调制波移相控制技术,即逆变器两个桥臂采用相同的载波,而两个调制波则具有一定的相位差。同时针对移相调压过程中出现的输出线电压电平变化问题,进行了详细的理论分析和公式推导,得出了输出线电压电平变化的临界相位差。最后给出了实验结果,验证了理论分析的正确性和可行性。 |
| 关 键 词： | 逆变器 中点箝位 移相控制 载波层叠 |

| Abstract: | In order to adjust the output voltage of single phase three-level inverter,phase shift technique is introduced based on modulation strategy of multi carrier disposition.Two bridges of the inverter use the same carrier wave,and there is some phase difference between two modulation waves.Then,it is found that the level of output line voltage will be changed under different phase difference.This problem is analyzed in detail and the critical phase difference is calculated to explain it.At last,the theory analysis is verified by the experiment. |
| Keywords: | inverter neutral point clamped phase shift control carrier disposition |
