In this paper, the authors propose a new strategy for the command of t
he three-phase voltage inverter's switches. After a recall of the prin
ciple on which the Delta-Sigma modulation single-phase converter works
, they emphasize the avantages it provides and they show how this stra
tegy can be extended to the three-phase voltage inverter by a vectoria
l approach. Compared to usual modulations and space vector modulation
techniques that are now frequently to be found, for identical average
switching frequency, this process improves the quality of the output v
oltages applied to the load. The numerical simulation results are pres
ented.
