| 摘 要： | 提出了一种新型的直接功率控制策略,改善了PWM整流器的传统直接功率控制的性能。通过对传统直接功率控制的分析,推导出一个新的开关表,可以显著地改进PWM整流器的无功功率控制性能。MATLAB仿真验证了这种新型的直接功率控制可以有效降低电流谐波总畸变率,提高无功功率的可控性,有效提升了PWM整流器的性能。

| Abstract: | A new Direct Power Control (DPC) of PWM rectifier was introduced. This strategy can improve the performance of PWM rectifier based on classical DPC. Through analysis of classical DPC,a new switch table can be deduced which promote the efficiency of reactive power control of PWM rectifier. The results of MATLAB simulation showed that the new DPC can reduce the current total harmonic distortion,improve the reactive power control and better the function of PWM rectifier. |
