نویسندگان
چکیده
This paper compares and evaluates the performance of Sinusoidal Pulse Width Modulation (SPWM) and Space Vector Pulse Width Modulation (SVPWM) techniques for a three-level inverter by cascading two two-level inverters. In this topology, four power semiconductor switches are used per phase and a total of twelve switches are required. The simulation study shows that SVPWM is superior to SPWM in the aspects of better DC-bus utilization and offering better spectral performance.

Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...
