A refined space vector modulation scheme for
multilevel inverters, using only the instantaneous sampled
reference signals is presented in this paper. The proposed
space vector pulse width modulation technique does not require
the sector information and lookup tables to select the
appropriate switching vectors. The inverter leg switching times
are directly obtained from the instantaneous sampled
reference signal amplitudes and centers the switching times
for the middle space vectors in a sampling time interval, as in
the case of conventional space vector pulse width modulation.
The simulation results are presented to a fivelevel inverter
system for dualfed induction motor drive. The dualfed
structure is realized by opening the neutralpoint of the
conventional squirrel cage induction motor. The fivelevel
inversion is obtained by feeding the dualfed induction motor
with fourlevel inverter from one end and twolevel inverter
from the other end.
