Abstract
Current PWM rectifier links in the network side using LC devices help filter harmonics and commutation, LC type filter has second order characteristics, the presence of the resonance peak and the resistor of capacitance is also very small, which is easy to cause the current waveform distortion in the transient process or in steady-state oscillation in the case of the presence of the control system disturbances. This paper presents a control strategy using input shaping techniques and combining inductive voltage feedback, which can effectively inhibit distortion and vibration caused by LC links under the external interference or current command change. Input shaping technique can effectively suppress the vibration of small damping system, inductor voltage feedback control can suppress side current waveform distortion in the external interference. This paper combining the both advantages can effectively solve the current mode pulse width modulation rectifier side current oscillations and distortion. 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.关键词
