Iron Loss Analysis of PMSM in Different Driving Conditions

机车电传动, 2012
The amount of PM iron loss varied according to different driving conditions. In this paper, the actual current of the prototype motor was used to perform 2D finite -element analysis and obtain the flux-density waveform in conditions of no-load, maximum ...

Non-Integral AC Capacitor Voltage Calculation Method for Shunt Hybrid Active Power Filter

IEEE Access, 2023
This paper introduces a novel non-integral method for calculating AC capacitor voltage in shunt hybrid active power filters (SHAPFs). These filters commonly use passive power filters (PPFs) that can introduce voltage containing harmonics into the AC ...

Assessing the effects of power quality on partial discharge behaviour through machine learning [PDF]

, 2010
Partial discharge (PD) is commonly used as an indicator of insulation health in high voltage equipment, but research has indicated that power quality, particularly harmonics, can strongly influence the discharge behaviour and the corresponding pattern ...

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics

Advanced Functional Materials, EarlyView.
2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

Harmonics suppression effect of the quasi-periodic undulator in SASE free-electron-laser

, 2013
In this paper, the harmonics suppression effect of QPUs in SASE FEL is investigated. The numerical results show that the harmonics power is reduced by using QPUs, but the fundamental radiation power also has a pronounced decrease as the saturation length

Harmonic analysis

2004 IEEE Electro/Information Technology Conference, 2004
This paper describes a method of calculating the transforms, currently obtained via Fourier and reverse Fourier transforms. The method allows calculating efficiently the transforms of a signal having an arbitrary dimension of the digital representation by reducing the transform to a vector-to-circulant matrix multiplying.
