This paper presents an input current ripple analysis of inverter fed dual three-phase induction motors. Four types of modulation strategies are compared. The first is single-carrier with zero phase displaced modulation signals, second is single carrier with 30° phase displaced modulation signals, third is double carrier with zero phase displaced modulation signals, and fourth is double carrier with...
Analysis method for input current ripple in several configuration of six-legs twelve-devices inverters is proposed in this research. It begins with deriving the expression for the rms value of six-phase PWM inverters as a function of reference signal. Based on its load, there are two kinds of inverters that is used in this research, which are double winding (dual stator) and dual fed. Double winding...
