| 摘 要： | 本文在分析二极管箝位型逆变器直流侧母线电容电压不平衡原因的基础上，提出了一种采用滞环控制的辅助斩波电路。仿真结果表明，应用这种电路可以实现直流侧电容电压平衡，同时逆变器输出电压具有较好的谐波性能。

| Abstract: | In this paper, an auxiliary chopper circuit which is controlled by hysteresis-band is proposed on the foundation of analyzing the mechanism of dc bus voltage unbalance in diode-clamped multilevel inverter. The simulation results indicate that employing this circuit can maintain the voltage balance, and the output voltage exhibits good harmonic characteristics. |
