Model-predictive current control (MPCC) is widely recognized as a high-performance strategy of permanent magnet synchronous machine (PMSM) drives due to its quick response and simple principle. It uses cost function select the best voltage vector minimizing error between reference value feedback value. However, only one applied during period, it fails give satisfactory performance limited vectors, especially in case two-level converters. This paper proposes an improved MPCC for PMSM drives,...
Following our recent study demonstrating predominant Li-ion hopping conduction in sulfolane (SL)-based highly concentrated electrolytes with LiBF4, LiClO4, and lithium bis(fluorosulfonyl)amide, herein a systematic on transport properties coordination of SL-based bis(trifluoromethanesulfonyl)amide was performed. In the region, Li ions clearly diffuse faster than SL TFSA anions. The two oxygen atoms sulfonyl group tend to coordinate different neighboring anions form ionic clusters ions,...
Nonradiative losses caused by defects are the main obstacles to further advancing efficiency and stability of perovskite solar cells (PSCs). There is focused research boost device performance reducing number deactivating defects; however, little attention paid defect-capture capacity. Here, upon systematically examining capacity, highly polarized fluorinated species designed modulate dielectric properties material minimize its radius. On one hand, polar strengthen defect dielectric-screening...
The safety issue of lithium batteries based on liquid electrolytes has become the focus attention, especially when are exposed to mechanical, thermal, or electrical abuse conditions. To address this issue, gel polymer (GPEs) have attracted widespread interest due property solid–liquid coexistence with higher ionic conductivity, flexibility, and safety. In work, a poly(vinylidene-fluoride-co-hexafluoropropylene) (PVDF-HFP)/poly(methyl methacrylate) (PMMA) matrix GPE, containing...
Sparingly solvating electrolytes are an emerging class of used in Li–S batteries. In this type electrolytes, polysulfide dissolution and shuttling can be suppressed, resulting high Coulombic efficiency cycle life. To optimize the for energy density cells, effects solubility Li ion transport properties on battery performance were investigated tetraglyme (G4)-based solvate ionic liquids [Li(G4) x ][TFSA] a sulfolane (SL)-based concentrated electrolyte [Li(SL) 2 ][TFSA], which both diluted with...
Conventional model predictive current control (MPCC) applies only one vector during period, which produces large torque and flux ripples high harmonics in permanent magnet synchronous motor (PMSM) drives. Recently MPCC with duty cycle has been proposed to improve the steady state performance by applying non-zero null period. However, prior method requires lots of calculations predictions find optimal voltage vectors calculate their respective duration. Different from enumeration-based MPCC,...
Polymer electrolytes (PEs) are predicted to be an alternative liquid for lithium-ion batteries (LIBs) since they can overcome the problems of leakage and electrolyte flammability issues. However, polymer often suffer from disappointing cracks or breakage, which will lead short circuits bring some safety Furthermore, undesirable ionic conductivity at room temperature also limits their practical application. Here, a novel gel (GPE) was proposed. The cross-linking network formed by adding...
This is the first practical demonstration of a next-generation graphite–Li2S battery using high-load Li2S cathode on porous current collector and small amount single electrolyte. promising material for Li–S batteries, but it must be mixed with conductive substrate owing to its insulating properties. We prepared Li2S/C composites commercially available carbon-based materials as carbon hosts agents reduction Li2SO4 precursor Li2S. Intimate contact between composite constituents was achieved in...
The effectiveness of nonlinear flux observer has been validated in practical application. However, it is not easy to tune the gradient search gain. sensitive parameter variation and also stability can be greatly affected by This paper proposes an improved enhance performance. proposed method utilizes for both magnitude phase rotor, which changes error dynamic equations. Further, brings benefits smaller estimation quicker responses, since convergence path more reasonable. In addition,...
