| 摘 要： | 三相电流型PWM整流器在交流侧采用LC滤波器来滤除谐波,由于二阶LC滤波器的阻尼系数较小,容易引起网侧电流振荡。为此文中提出滤波电容电压反馈的有源阻尼控制,能够在不消耗有功功率的前提下,有效地滤除网侧电流谐波。通过仿真分析可知,提出的电容电压反馈能抑制网侧电流振荡。

| Abstract: | 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. |
