Abstract
In a common dc link dual-fed Open-End Winding Permanent Magnet Synchronous Motor (OEW-PMSM) topology it is well known how the additional flow of a Zero-Sequence Current (ZSC) is permitted. The low Zero-Sequence Impedance (ZSI) characteristic of high speed machines leads to high intensity and high frequency ripple of the ZSC. Therefore there is the necessity to eliminate the Zero-Sequence-Voltage (ZSV) produced by the two Voltage Source Converters (VSCs) that feed the machine. Furthermore the non-sinusoidal back Electro Magnetic Force (back EMF) causes the circulation of a third harmonic ZSC. An OEW-PMSM high speed starter-generator fed by a dual-inverter with single dc link is considered. Part I of this work proposes a modulation for the considered topology able to eliminate instantaneously the ZSV produced. In this paper a detailed analysis of the Dead Time (DT) effect on the ZSV has been carried out and a novel hysteresis control for the ZSC using the DT as a control action is presented. The DT produces a ZSV distortion on the zero axis that can be used to control the third harmonic ZSC flowing due to the non-sinusoidal machine back EMF.
