Reducing circulating currents in interleaved converter legs under selective harmonic elimination pulse-width modulation
Konstantinou, Georgios; Pou Félix, Josep; Capellá Frau, Gabriel José; Ceballos Recio, Salvador; Agelidis, Vassilios (2015)
Text en actes de congrés
Accés obertInterleaving of voltage source converter legs enables higher output currents per phase, effectively increasing the power rating without increasing semiconductor ratings. Different switching patterns between the converter ... -
Single-carrier phase-disposition PWM implementation for multilevel flying capacitor converters
Ghias, Amer M.Y.M.; Pou Félix, Josep; Capellá Frau, Gabriel José; Agelidis, Vassilios; Aguilera, Ricardo P; Meynard, Thierry A. (2015-10-01)
Article
Accés obertThis letter proposes a new implementation of phase-disposition pulse-width modulation (PD-PWM) for multilevel flying capacitor (FC) converters using a single triangular carrier. The proposed implementation is much simpler ... -
Single-carrier phase-disposition PWM techniques for multiple interleaved voltage-source converter legs
Konstantinou, Georgios; Capellá Frau, Gabriel José; Pou, Josep; Ceballos Recio, Salvador (Institute of Electrical and Electronics Engineers (IEEE), 2017-10-26)
Article
Accés obertInterleaved converter legs are typically modulated with individual carriers per leg and phase-shifted PWM (PS-PWM) as it facilitates current balancing amongst the legs. Phase-disposition PWM (PD-PWM), despite the better ... -

Study and comparison of discontinuous modulation for modular multilevel converters in motor drive applications
Picas Prat, Ricard; Zaragoza Bertomeu, Jordi; Pou Félix, Josep; Ceballos Recio, Salvador; Konstantinou, Georgios; Capellá Frau, Gabriel José (Institute of Electrical and Electronics Engineers (IEEE), 2019-01-01)
Article
Accés obertDiscontinuous modulation applied to modular multilevel converters is an effective method for reducing the capacitor voltage ripples. In this paper, the discontinuous modulation is adapted and used in a motor drive application. ... -
Study of modulation techniques applied to full bridge single-phase inverters based on wide-bandgap semiconductors
Ferrer Arnau, Luis Jorge; Berbel Artal, Néstor; Capellá Frau, Gabriel José; Zaragoza Bertomeu, Jordi (2019)
Comunicació de congrés
Accés obertWide-band gap (WBG) devices are gradually replacing standard Si semiconductors in power converters. This is due to the fact that WBG devices exhibit lower capacitance and on-resistance and besides, as they can switch at ... -
Voltage-source-inverters with legs connected in parallel
Capellá Frau, Gabriel José (Universitat Politècnica de Catalunya, 2015-03-26)
Tesi
Accés obertThe number of applications that require the use of power converters has been continually increasing in the last years on account of environmental and economical concerns. The power to be processed by these converters has ...
