基于αβ坐标系的电流型PWM整流器有源阻尼控制
Active Damping Control of Three-phase Current Source PWM Rectifierunder αβ Coordinates
LC filter and aided switch devices are often used in AC side of three-phase pulse width modulation (PWM) current source rectifier (CSR). Although LC filter can filter harmonics effectively, it has the feature of resonance and exists resonance peak. The system oscillatory transient and supply current waveform distortion are caused by those, when the input of the system or load changed. Aiming at the above problems, a method of active damping control of the inductor voltage feedback under αβ coordinates is proposed. It does not require phase-locked loop control or dq coordinate decoupling. Combining with active damping control of inductive voltage feedback, the method is implemented under the αβ coordinate to suppresses LC filter resonance peak effectively. Finally, the effectiveness and practicability of the proposed method are verified by MATLAB simulation and experimental.
