Abstract :
This paper deals with flux harmonic distortion factor (HDF) and current ripple analysis for various discontinuous space vector PWM (SVPWM) techniques, applicable in conjunction with five-phase two-level inverter-fed ac motor drives. The analysis is based on the application of the recently developed polygon approach for multiphase systems. The results are compared throughout with the corresponding continuous SVPWM techniques. Two different SVPWM methods, based on different selections of the active vectors, are encompassed by the analysis. The analytical study is supported with simulation and experimental result, obtained using a five-phase induction motor.
