Various PWM methods for multi-phase (n>3) two-level voltage source inverters (VSIs) have been developed recently. Relatively little work has however been done in relation to switching harmonic properties of these PWM methods and their impact on current ripple. The purpose of this paper is to present an evaluation of the flux harmonic distortion factor (HDF) associated with the space vector PWM...
Multiphase variable-speed drives, supplied from two-level voltage-source inverters (VSIs), are currently considered for a number of industrial applications. Although various multiphase pulsewidth-modulated (PWM) schemes had been recently developed, very little has been reported with regard to the impact of these schemes on harmonic losses (current ripple). This paper presents a general analytical...
