Current and voltage shaping method via modified d–q transformation for the torque ripple compensation in PMSMs

open access: yesThe Journal of Engineering, 2019
This study deals with a novel control strategy for permanent magnet synchronous machines (PMSMs) to incorporate disturbance compensation features in the existing current controller maintaining at the same time the integrity of the reference tracking ...

Harmonics and unbalanced load compensation by a modular multilevel cascaded converter active power conditioner

open access: yesThe Journal of Engineering, 2019
This paper presents a novel control scheme for a modular multilevel cascaded converter (MMCC) functioning as an active power conditioner (APC) to control the reactive power, eliminate the current harmonics, and compensate unbalanced load current ...

Refinement of the Cast Microstructure of Hypereutectic Aluminum-Silicon Alloys with an Applied Electric Potential [PDF]

open access: yes, 2012
Hypereutectic aluminum-silicon (Al-Si) alloys are widely used in the aerospace and automobile industries because of their low density, excellent wear and corrosion resistance, low coefficient of thermal expansion, good strength, and excellent castability.

Imaging the electric field associated with mouse and human skin wounds

open access: yes, 2008
We have developed a noninvasive instrument called the bioelectric field imager (BFI) for mapping the electric field between the epidermis and the stratum corneum near wounds in both mouse and human skin.

Electric-current control of anomalous Hall effect

open access: yes
We demonstrate robust and reversible electric-current control of the anomalous Hall effect (AHE) in a two-dimensional WTe₂/Fe₃GeTe₂ (FGT) stack. Applying a current through Td-WTe₂ leads to a giant modulation of the AHE of the adjacent FGT layer, with the relative change of the AHE conductivity exceeding 180%.

Closed‐loop input current control strategy based on waveform similarity index for the emerging matrix converters with harmonic injection technique

open access: yesIET Electric Power Applications
Harmonic injection matrix converter (HIMC) achieves direct AC‐AC power conversion with maximum voltage transfer and reduced transistor capacity. However, the existing open‐loop current control method for HIMC may bring in low‐order harmonics if the ...

Static electric field detection and behavioural avoidance in cockroaches

open access: yes, 2008
Electric fields are pervasively present in the environment and occur both as a result of man-made activities and through natural occurrence. We have analysed the behaviour of cockroaches to static electric fields and determined the physiological ...

Anomalous Phenomena in Solid Dielectrics under High Electric Fields (Keynote)

open access: yes, 2009
Solid dielectrics have been used extensively in electrical and electronic industries. In the power industry, ultra high voltage transmission and cost saving of power equipment often result in that the dielectrics are operating under high electric fields.

Maximum Torque Per Ampere Control Strategy of a 5-phase PM Generator in healthy and faulty modes for tidal marine turbine application [PDF]

open access: yes, 2014
The work presented in this paper aims to propose a control strategy being able to extract efficiently energy from a fixed-pitch marine current turbine associated with a 5–phase Permanent Magnet Synchronous Generator (PMSG) in healthy mode and in faulty ...
