A Voltage Modulated DPC Approach for Three-Phase PWM Rectifier

摘要: In this paper, a voltage modulated direct power control for three-phase pulsewidth rectifier is proposed. With the suggested method, differential equations describing dynamics are changing from linear time-varying system into time-invariant one. way, conventional feedback and feedforward controllers applicable independent of active reactive powers. The proposed method has guaranteed that closed globally exponentially stable. A linearization also employed generating reference inner loops. Finally, some experimental tests conducted to verify its effectiveness.
