Multiphase PMSM and PMaSynRM flux map model with space harmonics and multiple plane cross harmonic saturation
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessMultiphase Synchronous Machines vary in rotor construction and winding distribution leading to non-sinusoidal inductances along the rotor periphery. Moreover, saturation and cross-saturation effects make the precise modeling ... -

Open AccessThispaperpresents the design and structure of aversatileworkbench simulator forevaluating the performance of a five-phase inverter andPermanent Magnet assisted Synchronous Reluctance Motor(PMa-SynRM). The simulatorallows ... -
A comprehensive analysis of SVPWM for a Five-phase VSI based on SiC devices applied to motor drives
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessThis paper presents a comprehensive analysis of SVPWM for a five-phase VSI based on SiC devices applied to motor drives. The modulation techniques analyzed use medium and large vectors to reach the reference vector. The ... -
Study of modulation techniques applied to full bridge single-phase inverters based on wide-bandgap semiconductors
(2019)
Conference lecture
Open AccessWide-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 ... -
Efficiency analysis of wide band-gap semiconductors for two-level and three-level power converters
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Open AccessPower devices based on wide band-gap materials are emerging as alternatives to silicon-based devices. These new devices allow designing and building converters with fewer power losses, and are thus more highly efficient ... -
Submodule power losses balancing algorithms for the modular multilevel converter
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Conference report
Open AccessTolerance and component aging can cause significant differences in the capacitance values of the submodules (SMs) in a modular multilevel converter (MMC). Depending on the modulation technique, capacitance mismatches may ... -

Mathematical efficiency modeling of static power converters
(2015)
Conference report
Open AccessThis paper presents a review and a comparative analysis between mathematical models for the efficiency of power converters. Two different types of models are considered, being one for converters subject solely for output ... -
Reducing circulating currents in interleaved converter legs under selective harmonic elimination pulse-width modulation
(2015)
Conference report
Open AccessInterleaving 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 ... -
Modelling harmonics drawn by nonlinear loads
(Institute of Electrical and Electronics Engineers (IEEE), 2015)
Conference report
Restricted access - publisher's policyThis paper is devoted to obtain a model of nonlinear loads (NLL) connected to LV electric networks, in order to predict the consequences of including parallel active or passive filters. The model is based on Neural ... -
