2013 Brazilian Power Electronics Conference, 2013
This paper discusses three-phase high power factor AC-to-DC current source converters appropriate for Electric Vehicle (EV) battery charging systems. The AC grid interfaces are multilevel current source rectifiers constructed from standard power electronic circuits that have their fast-switched semiconductors and output inductors replaced with several ...

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
Due to the nonstationary characteristic of the electric locomotives in electric traction systems, the equivalent grid impedance changes frequently, which may lead to detrimental effect on the control system of electric traction PWM rectifiers. The mathematical model of an electric traction PWM rectifier is established, and the double-loop control ...

Advanced Photonics Congress (IPR, Networks, NOMA, SOLITH, SPPCom)
There is an important opportunity to further innovate and improve active metamaterials for the infrared regime over the state-of-the-art, as metasurfaces become less passive, functional for infrared wavelengths/frequencies, and some use interesting nonlinear effects.

Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting, 2003
The authors propose a method for suppressing the generation of high harmonic currents on the AC side of the diode rectifier circuits in AC electric railways by connecting the CR series circuit in parallel with the load on the DC side of the rectifier circuits. A theoretical analysis of a single-phase rectifier circuit adopting this method is presented.

Journal of Materials Chemistry, 2000
We found unimolecular rectification in a single molecule, (N-hexadecylquinolin-4-ium-1-yl)methylidenetricyanoquinomethanide, 1, in which the ground state is zwitterionic: D+–π–A−, and has a large dipole moment (43 D) while the first excited state is undissociated: D0–π–A0 (and has a smaller moment, between 3 and 9 D).
