Abstract :
This paper describes the harmonic evaluation of three-phase carrier-based multilevel (2-level to 5-level) PWM inverter methods. The harmonic distortion determining factor (HDDF), which represents the intrinsic spectral property of individual PWM methods, is calculated for each of the multilevel PWM methods, and is used as the common quality index. Almost all the carrier-based PWM schemes that have been proposed so far are considered. HDDF values are helpful for selecting inverter system parameters for AC motor drive applications because they can be used for predicting the current harmonics or torque ripple in AC drives
