A general SVM algorithm for multilevel converters considering zero-sequence component control
31st Annual Conference of IEEE Industrial Electronics Society, 2005. IECON 2005., 2005Space vector modulation (SVM) scheme plays a significant role in high-voltage high-power applications of multilevel converters for its good performance. This paper presents a novel general SVM algorithm for multilevel converters. It includes two parts: one is control of fundamental component of three-phase outputs corresponding to reference vector; the

ABSTRACTThis paper describes the design of a dynamic voltage restorer (DVR) that can simultaneously protect several sensitive loads from voltage sags in a region of an MV distribution network. A novel reference voltage calculation method based on zero-sequence voltage optimisation is proposed for this DVR to optimise cost-effectiveness in compensation ...

This paper develops and analyzes a methodology for detecting stator winding inter-turn faults in surface-mounted permanent magnet synchronous motors. The proposed methodology is based on monitoring the zero-sequence voltage component having into account the effects of the inverter that usually feeds the machine.
