Abstract :
Sigma-Delta Modulation (SDM) technique, well known in the telecommunication industry, has recently shown its feasibility in power converters. In this paper, the application of SDM for the voltage modulation in multiphase drives is analyzed. Simulation results compare SDM with other advanced modulation techniques, like the Space Vector Modulation method, and confirm its viability in an asymmetrical dual three-phase AC machine.
