This work is part of the innovative "Active Generator" (AG) project. AG is a concept that suggests a new arrangement of the turbine-generator line of a high power utility (a few hundred of MW) in order to de-synchronize the rotation speed of the turbine-ge ...
In the frame of the development of a very high speed synchronous drive, a DC/DC converter is studied. In this context, this paper presents the comparison between two two-commutation-cell topologies. A multichannel and a multilevel converter are formally co ...
Optical burst switching (OBS) is able to operate under both asynchronous and synchronous burst departures. Although the asynchronous approach is generally assumed in OBS owing to its simplicity and low technical requirements, it has been shown that perform ...
Multiphase series-connected motor drives can be supplied from a two-level voltage source inverter (VSI), which has either a prime or a composite number of legs (phases). It has been shown recently that, in the case of a prime number of inverter/machine pha ...
This paper presents a multi-port isolated DC-DC converter for DC applications. A three-port structure is presented, characterized with full bidirectional power flow and simple control. Galvanic isolation is achieved by means of a multi-winding medium frequ ...
Flux harmonic distortion factors (HDFs) of two space vector pulse width modulation (SVPWM) schemes, aimed at sinusoidal output voltage generation with five-phase voltage source inverters, have been evaluated in Part 1 of this paper. Analytical consideratio ...
Modern trains with active line-side converters are currently the state-of-the-art technology in the traction industry. In such systems, the active line-side converter of the drive system can be exploited for power quality improvement purposes. In this pape ...
This paper presents an alternative way for the current regulation of single-phase voltage-source dc-ac converters in direct-quadrature (dq) synchronous reference frames. In a dq reference frame, ac (time varying) quantities appear as dc (time invariant) on ...

This paper presents a new parametric model of a single-active-bridge (SAB) converter with a variable number of phases. The soft-switching behavior and the design of snubbers are also analyzed. The analytical study is validated using PLECS simulation softwa ...
Multiphase variable-speed drives supplied from two-level voltage source inverters (VSIs) are, at present, contenders for numerous industrial applications. Various pulse width modulation (PWM) methods for multiphase VSIs, aimed at sinusoidal output voltage ...
