| 摘 要： | 介绍了一种新型的三相三电平中性点二极管箝位PWM整流器电路拓扑,在详细分析该电路工作模式的基础上,提出了一种新颖的基于PWM整流器平均模型的定频PWM控制策略。仿真结果表明,该PWM整流器可以有效地抑制注入电网的谐波,减小开关管应力,实现功率因数可调以及能量的双向流动。

| Abstract: | A novel three-phase three-level neutral-point-clamped PWM rectifier is presented,the working mode of the rectifier is analysed,and a novel PWM constant-frequency control method based on the average model of PWM rectifier is derived in detail.The simulation results show that the harmonics is suppressed effectively,the voltage stress of power switches is reduced,the power factor is adjusted,and the bi-directioned flowing of the energy is implemented. |

| Keywords: | rectifier PWM power factor / three-level Neutral-Point-Clamped(NPC) |
