This article presents a novel flux-switching (FS) machine adopting star-array permanent-magnets (PMs), termed as star-FSPM machine. In comparison with the conventional spoke-FSPM machine, proposed one can achieve not only enhanced flux-concentration effect, but also enlarged stator-slot area, thus improving PM utilization ratio and torque density. The harmonic characteristics of both field arma...

Abstract Converter transformers are an interface point of HVDC frameworks and basic hardware from activity reliability view point. turned off intentionally under planned support un-deliberately during fault conditions. Random energization transformer delivers high inrush currents due to core saturation asymmetries endanger equipment health. In this paper, charging approach has been proposed. By...

We propose a new strategy for ultrafast magnetization reversal of nanomagnets. Due to the Inverse Faraday Effect, circularly polarized optical pulses induce a pulsed magnetic flux in materials with large magneto-optical susceptibility. Alternatively, intense optical pulses can induce a pulsed magnetic flux by means of ultrafast demagnetization of a metallic thin film or multilayer with a perpen...
