An improved IPT-PLL technology for single-phase grid-connected inverters in complex power grid conditions

Abstract Aiming at the common problems of frequency variations and harmonics in complex power grids, an improved inverse Park transform phase locked loop (IPT-PLL) technology for single-phase converters suitable for micro grid systems is proposed. Firstly, in the phase detection of PLL, the α compon...
