This paper investigates a back to back test simulation of an interior permanent magnet (IPM) synchronous machine with fractional slot concentrated windings (FSCW). The studied machine is designed to equip a floating vertical axis wind turbine. The principal characteristics and the structure of the machine are presented, as well as the back to back test principle. The parking brake mode is investigated...
This paper presents an analytical approach to characterize a flux concentration permanent magnet synchronous machines (PMSM) with fractional slot concentrated winding (FSCW). The very particular configuration of the studied machine leads the authors to associate a fictive winding to the stator coils in order to be able to determine the Ld and Lq inductances. Experimental measurements, done on the...
Background In an effort to better understand the molecular networks that underpin macrophage activation we have been assembling a map of relevant pathways. Manual curation of the published literature was carried out in order to define the components of these pathways and the interactions between them. This information has been assembled into a large integrated directional network and represented graphically...
This paper introduces a special mx3 matrix converter connected between the stator of a poly-phased synchronous generator and a power grid. Some commutations of the chosen switching scheme induce voltage surges due to leakage inductances of the generator. This paper then presents an analysis of a passive solution using capacitive and resistive elements to control the magnitude of this voltage overshoot...
