Digital PLL Control for Grid-Connected Photovoltaic System

계통 연계형 태양광 발전 시스템을 위한 디지털 PLL 제어

The frequency and Phase angle of the utility voltage are important in many industrial systems. In this paper, the analysis and generalized approach of single-phase PLL control have been presented. The experimental results have been presented and demonstrated the feasibility of proposed methods.
