Abstract
An input current-ripple analysis of nine-phase pulse width modulated (PWM) inverter is presented in this paper. The current-ripple is analyzed using a frequency domain approach. Two configurations of nine-phase inverter (symmetrical and asymmetrical) are analyzed. Analysis results show that symmetrical configuration has lower input current-ripple compared to asymmetrical configuration. Several experimental results are included to show the validity of the proposed analysis method. © 2011 IEEE.
