Sa. Papathanassiou et Mp. Papadopoulos, COMMUTATION ANGLE ANALYSIS OF THE SLIP ENERGY RECOVERY DRIVE, IEEE transactions on energy conversion, 13(1), 1998, pp. 21-26
A well known characteristic of the slip energy recovery drive (SERD) i
s the large commutation overlap of the rotor side rectifier, which com
promises the accuracy of simplified dq models often used for its simul
ation, In this paper the variation of the rectifier commutation angle
and the factors that determine its magnitude are investigated using a
detailed hybrid abc-dq model of the SERD, the accuracy of which is val
idated hy experimental results. The dependence of the shown for a case
study drive and practical relations are deduced which permit the eval
uation and a posteriori correction of the steady state error of simpli
fied do models, where the commutations and converter harmonics are ign
ored.
