摘要
文中对串联混合电力滤波器抑制谐波的原理进行了分析。为了检测单项系统的谐波电流,提出一种基于虚拟三相法和瞬时无功理论的谐波检测方法,并且对串联滤波逆变器的直流侧电压的控制进行了讨论。仿真结果证明了其有效性。
The basic principles for suppressing the harmonics of the series hybrid active power filter（SHAPF） are analyzed. In order to detect the harmonic and reactive currents of a single-phase power system, a new way based on virtual three-phase method and instantaneous reactive power theory. Furthermore the control method of PWM inverter in the series APF and for regulating its DC side voltage are discussed. Some simulated results are provided for demonstrating the effective of the proposed approach.
