Active control for medium-frequency transformers flux-balancing in a novel three-phase topology for cascaded conversion structures
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
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 ... -
Dynamic modeling and simulation of a pressurized alkaline water electrolyzer: a multiphysics approach
In this paper a dynamic model for the simulation of pressurized alkaline water electrolyzers is presented. The model has been developed following a multiphysics approach, integrating electrochemical, thermodynamic, heat ... -
Hydrogen educational activities developed by APERNA: a renewable-energy student association
In this paper, we present APERNA, a recently-created student association at Public University of Navarre (UPNA) with the aim of promotion of renewable energies. -
Modelling and operation of 6-pulse thyristor rectifiers for supplying high power electrolyzers
This paper presents a detailed analysis of a 6-pulse thyristor rectifier aimed at supplying high power electrolyzers. For this purpose, an analytical model of the three-phase controlled rectifier with AC-side inductance ... -
Novel three-phase topology for cascaded multilevel medium-voltage conversion systems in large-scale PV plants
Solar photovoltaic renewable energy systems are expanding in the power sector thanks to its increasingly competitive prices. Traditionally, large-scale PV plants have reduced their cost by increasing the power ratings of ... -
Toroidal inductor design in multilevel DC-DC electric vehicle battery charger including high-frequency effects
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
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 ...
