A Phase-Locked Loop algorithm for single-phase grid-connected systems with sub and interharmonics immunity

Abstract

This paper proposes a new closed-loop synchronization algorithm, PLL (Phase-Locked Loop), for applications in power conditioner systems for single-phase networks. The structure presented is based on the correlation of the input signal with a complex signal generated from the use of an adaptive filter in a PLL algorithm in order to minimize the computational… (More)
