摘要
为保证指定次谐波补偿有源滤波器(Active Power Filter,APF)取得更好的补偿效果,主要研究了有源滤波器的锁相环(Phase Locked Loop,PLL)技术。本文根据dq变换原理,提出了一种基于反正弦函数加速收敛的新型有源滤波器锁相环技术。该技术在误差范围内,可实现绝大部分相位偏移范围内的1次调节锁相。与传统的基于dq变换的锁相环技术相比,新型锁相环技术具有明显的速度优势和灵活性。最后,仿真与实验结果验证了上述分析的正确性。
In order to guarantee the compensation of APF Power Filter(APF), the PLL technology of ac-tive filter is studied. In this paper, based on the principle of dq transform, a new active filter phase-locked loop technique based on anti sinusoidal acceleration was proposed. In the range of error, this tech-nique can realize the 1 phase locking in most phase shift range. Compared with traditional PLL technologybased on dq transform, the new PLL technology has obvious speed advantage and flexibility. Finally, simula-tion and experimental results verified the correctness of the above analysis.
