Decoupling control of a series-connected two five-phase PMSM supplied by a three-level five-level inverter

Abstract

This paper presents independent vector control of two five-phase permanent magnet synchronous machines, 'PMSMs' series-connected fed by a three-level five-phase inverter. Fully decoupled control of both machines is possible via an appropriate phase transposition while connecting the stator windings serial. The control system multi-machines classic based on vector control with conventional inverters comprise various problems are related to low power quality, pressure on motor bearing, etc. In this paper, decoupling control of a series-connected two five-phase PMSM powered by a three-level five-phase inverter is presented. Simulations results are presented and discussed for the whole system.
