| 摘 要： | PWM整流器大多采用基于电压定向的双环控制策略,该策略可能存在计算量大、有相位检测误差和电流环解耦不彻底等问题。针对电压定向双环控制策略存在的以上问题,提出了基于瞬时功率理论的双闭环控制方法,此方法有效地克服了电压定向控制策略的不足。实验结果表明采用所提出的方法控制整流器,系统具有优良的动态特性和静态特性。

| Abstract: | Dual loop control method based on voltage-oriented is usually applied to control PWM rectifier.The control method has some disadvantages such as error of detecting phase angle,greatly computing quantity and incompletely decouple current loop.According to these disadvantages,the dual loop control method based on the instantaneous power theory was proposed.The above disadvantages were overcome.The control system based on the proposed method for PWM rectifier has excellent dynamical and steady-state performance,which is verified through results. |
