Popis: In this paper, a comparison of phase-shifted carrier PWM (PSC-PWM) techniques on a three-phase CHB-MLI is presented. First, principles of three different PSC-PWM techniques are investigated in detail in terms of their PWM generations and frequency spectrums. Then, total harmonic distortion and magnitude of the fundamental frequency component parameters are observed for different PSC-PWM techniques on a three-phase CHB-MLI with equal and unequal DC voltages for all phase and line voltages as well as line current.
