Abstract
An input current ripple analysis of PWM inverter fed double-stator AC drive system is proposed in this paper. The expression of rms input current ripple of PWM inverter as a function of phase difference between stator windings is derived. It is found that the optimum phase difference that results in minimum input current ripple is 60o. Several experimental results are included to show the validity of the proposed analysis method. © 2013 IEEE.
