A modified pulse width modulation strategy for single-phase multilevel quasi-Z-Source inverters has been proposed in this paper, which reduces switching action applying to traditional simple boost control or maximum constant boost control. Therefore, this strategy yields lower switching loss and higher system efficiency. A Seven-level quasi-Z-Source inverter, based stand-alone photovoltaic system...
This paper studies about the effects of dynamic eccentricity fault on double rotor-one stator axial flux three-phase coreless permanent-magnet machine using three-dimensional finite-element analysis. To the best awareness of the authors, effects of dynamic eccentricity in this type of machine have not been studied before. Hence, the definition of dynamic eccentricity fault (DEF) and air gap length...
