Phase-error correction by single-phase phase-locked loops based on transfer delay [PDF]
, 2015 Comparative studies of different single-phase phase-locked loops (PLL) algorithms have been made. They show that the PLL based on sample delay (dPLL), presents the lowest computational load and is as robust as the three-phase synchronous reference frame ...
