Different from the deadtime effect of conventional twolevel inverters, zerosequence voltage and current could be produced by the switching dead time of dual inverters in openend winding motor drives, and consequently low frequency harmonics emerged in winding currents which led to negative effects on performance of the drive systems. A compensation scheme for the zerosequence voltage produced by the switching dead time was proposed. By inserting compensation voltage vectors, the method counteracted the zerosequence voltage produced by the switching dead time using that of the compensation voltage vectors. Therefore, the zerosequence voltage and current of the system could be reduced. The proposed compensation strategy was validated by the simulation and experiments in an openend winding induction motor drive system.
