this is three phase PLL easily get locked to fundamental component of voltage even in presence of harmonics.
please check notation used for q & d vector...its bit different then conventional..
it is based on varing the delta of space vector pulse width modulator.Basic description is also given in file itself
change in Vdc are sensed & are used to generate the current reference only at zero crossing of voltage. otherwise may cause imbalance
three phase three level space vector based pulse width modulation with optimal switching

here current error is converter to hexagonal band. inner & outer band corresponds to medium & large vector. here voltage vectors are 30 degree shifted to what is have in case of normal space vector
