| 摘 要： | 基于最优电压空间矢量原理,提出了适用于并联型有源电力滤波器的双滞环电流控制新方法,达到了减少高次谐波分量、加快响应速度的目的。利用具有较大带宽的迟滞比较器采用“尝试-错误-校正-保持”的方法确定了参考电压空间矢量区域,通过引入电压空间矢量提高了直流侧电压利用率,降低了开关频率,改善了有源滤波器性能。仿真实验验证了该方法的可行性和有效性。

| Abstract: | A novel double hysteresis current control method for shunt active power filter(APF) based on optimal voltage space vectors is proposed and the purpose of quickening transient response and reducing high-order harmonic components is achieved. The spatial vector region of voltage reference is determined by a hysteresis comparator with wider bandwidth and its location can be quickly detected by a trial-error-correction-holding method, which is simple and reliable. The optimal voltage space vector is introduced into control system, which can increase the utilization of DC bus voltage, decrease the switching frequency and improve the efficiency of APF evidently. Simulation experiments verify the feasibility and effectiveness of the proposed method. |
