电容电压反馈的电流型整流器有源阻尼控制研究
Active damping control based on the LC filter capacitor voltage feedback techniques
Current PWM Rectifier links in the network side using LC devices help to filter harmonics and commutation, LC type filter was second order characteristics, the presence of the resonance peak and the resistor of capacitance is also very small, easy to cause the current waveform distortion in the transient process. This paper presents a control strategy using capacitor voltage feedback, which can effectively inhibit distortion caused by LC links under current command change. The performance of the proposed method is verified by simulation and experimental results, distortion of the line current is effectively reduced and the stability of the system is improved.
