摘要: This paper presents a novel frequency-adaptive Phase-Locked Loop (PLL) for single-phase grid-connected power converters. The orthogonal component in the rotating reference frame is generated by synthesis circuit which utilizes detected amplitude and phase. It's without using any additional circuits. Moreover, special improved PLL proposed to make sure work well under low-order harmonics distortion condition. These structures are simple easy implementation. In this paper, method analyzed its performance evaluated both simulations experiments.
