本文提出了一种新颖的和简单的直接功率控制的三相脉宽调制（PWM）整流器与恒定的开关频率使用空间矢量调制（DPC-SVM）。有功功率和无功功率被用作脉宽调制（PWM）控制变量，而不是被使用的三相线电流。此外，线电压传感器被虚拟通量估计器取代。讨论了该方法的理论原理。稳态和动态结果的DPC支持向量机，说明所提出的系统的操作和性能。结果表明，DPC-SVM具有算法简单、动态响应好、开关频率恒定等特点，特别是在电源电压不理想的情况下，能够提供正弦的线电流。实验结果表明，该系统具有良好的性能，验证了该系统的有效性.
This paper proposes a novel and simple direct power control of three-phase pulsewidth-modulated (PWM) rectifiers with constant switching frequency using space-vector modulation (DPC-SVM). The active and reactive powers are used as the pulse width modulated (PWM) control variables instead of the three-phase line currents being used. Moreover, line voltage sensors are replaced by a virtual flux estimator. The theoretical principle of this method is discussed. The steady-state and dynamic results of DPC-SVM that illustrate the operation and performance of the proposed system are presented. It is shown that DPC-SVM exhibits several features, such as a simple algorithm, good dynamic response, constant switching frequency, and particularly it provides sinusoidal line current when supply voltage is not ideal. Results have proven excellent performance and verify the validity of the proposed system.
