Abstract Reducing the thickness of solid polymer electrolytes can help to enhance energy density for solid‐state batteries. However, ultrathin still face difficulties in preparation methods, mechanical properties, and interface instability. Herein, a free‐standing, scalable, electrolyte with 10 µm is reported. It achieved through situ thermal curing after filling porous electrospun polyacrylonitrile fiber membrane poly(ethylene glycol) diacrylate‐based electrolyte. Impressively, it...
This article proposes a modular seven-leg switched reluctance motor (SRM) drive with flexible winding configuration and fault-tolerant capability. In traditional SRM drives, the connection is fixed, where speed regulation range ability are both limited. To solve these issues, topology proposed, each phase divided into two segments, can be flexibly to achieve wide range. At low speed, segments connected in series for higher output torque, while parallel employed at high extend addition, swift...

A high-performance fully digital controller has been designed for the drive of a 50-kW four-phase switched reluctance (SR) motor built hybrid electric vehicle (HEV). The SR machine is specifically and manufactured to have high power density low acoustic noise. based on advanced signal processor (DSP) with internal CAN interface-TMS320F2406 complex programmable logic device (CPLD)-EPM7128S. experimental results show that met system specification requirement, satisfactorily.
Abstract Permanent magnet synchronous motor (PMSM) drive systems have been increasingly applied in all kinds of high‐power AC drives because their inherent advantages good performance, rapid dynamic response, as well high reliability and efficiency. Precise control the system traditionally depends on shaft encoder, but presence encoder could result increased cost volume, reduced reliability, etc. Therefore, development sensorless techniques is important to avoid above issues by elimination...
This article proposes an optimal active disturbance rejection control (ADRC) strategy for permanent-magnet synchronous motors (PMSMs), to improve the speed performance under periodic and aperiodic disturbances. First, harmonics weakness of conventional linear ADRC are analyzed, ability is found be degraded due limited bandwidth extended state observer (ESO). To enhance ability, a novel double-stage-ESO (2S-ESO) proposed, which integrates advantages both cascaded-ESO quasi-resonant...
Nickel-rich layered cathode materials, such as LiNixMnyCo1-x-yO2 (NMC), are essential for high-energy-density lithium-ion batteries used in electric vehicles due to their higher specific capacities compared lower nickel-content analogs. However, these materials suffer from structural instability, which becomes increasingly severe the nickel content rises. Despite significant importance, intrinsic change mechanisms of nickel-rich cathodes, especially at practical cycling rates, remain...
For conventional HTS synchronous generator, the superconducting (SC) field windings or armature are rotating, which could complicate their industrial feasibility for offshore wind generation. In order to overcome this drawback, a kind of double-stator flux modulation generator (HTS-DSFMG) without rotating is proposed. This paper compares electromagnetic performance 10-MW generators with two different topologies, i.e., iron-cored stators both and coils, air-cored stator windings. addition,...
In this article, a novel phase current reconstruction strategy for five-leg dual-inverter (FL-DI) fed open-winding permanent magnet synchronous motor (OW-PMSM) drive is put forward. Benefiting from the doubling of power legs, OW-PMSM endowed with outstanding fault-tolerant ability. When an open-circuit fault occurs, automatically turns to postfault two-phase operation. By reconfiguring wiring method, FL-DI topology obtained, and three-phase operation realized. However, flow path changes...
Data deduplication, though being efficient in removing duplicate chunks, introduces chunk fragmentation which decreases restore performance. Rewriting algorithms are proposed to reduce the fragmentation. Delta compression is often used as a complement for data deduplication further improve storage efficiency. We observe that delta new type of stemming from improper chunks base fragmented. The severely performance and cannot be addressed by existing rewriting algorithms. To address this...

We apply three-dimensional finite-element accurately analyze these...
