Active control for medium-frequency transformers flux-balancing in a novel three-phase topology for cascaded conversion structures
Lumbreras Magallón, David
; Barrios Rípodas, Ernesto ; Navarrete, Manuel; Balda Belzunegui, Julián; González Senosiain, Roberto ; Sanchis Gúrpide, Pablo (IEEE, 2020)
Contribución a congreso / Biltzarrerako ekarpena 
Efficiency and power density are important parameters in the design of power electronics converters. In many applications, low-frequency transformers are being substituted for medium-frequency and high-frequency transformers ... -
Analytical modeling of high-frequency winding loss in round-wire toroidal inductors
Elizondo Martínez, David ; Barrios Rípodas, Ernesto ; Sanchis Gúrpide, Pablo ; Ursúa Rubio, Alfredo (IEEE, 2020)
Contribución a congreso / Biltzarrerako ekarpena
Toroidal inductors are present in many different industrial applications, thus, still receive researchers' attention. AC winding loss in these inductors have become a major issue in the design process, since switching ... -

Toroidal inductor design in multilevel DC-DC electric vehicle battery charger including high-frequency effects
Elizondo Martínez, David ; Barrios Rípodas, Ernesto ; Sanchis Gúrpide, Pablo (IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena
Inductor filters, such as the ones implemented in DC-DC buck-boost converters for electric vehicle chargers, have a major impact on the converter weight, volume and cost. Thus, their design is key in order to obtain an ... -
Zero-loss switching in DC-DC series resonant converters under discontinuous conduction mode
Elizondo Martínez, David ; Barrios Rípodas, Ernesto ; Sanchis Gúrpide, Pablo (IEEE, 2021)
Contribución a congreso / Biltzarrerako ekarpena
Many thriving applications where isolation is required, such as traction and EV fast charging, implement solid-state transformers (SST). Half-cycle discontinuous-conduction-mode series resonant converters (HC-DCM-SRC) are ...
