摘　　要：为了改善PWM整流器的性能，提出了一种新型三相电压型SVPWM整流器的直接功率控制方案，给出了基于虚磁链的功率估算式，设计了基于神经元PID控制的功率调节器参数，对有功功率调节器和无功功率调节器之间的相互耦合关系进行了分析，并采用神经元智能PID控制对功率环进行调节。This paper introduces a novel and simple direct power control of three-phase Pulse Width Modulated （PWM） rectifiers using spacevector modulation （DPC-SVM）. The active and reactive powers are used as the 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 results of DPC-SVM that illustrate 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.
