Active control for medium-frequency transformers flux-balancing in a novel three-phase topology for cascaded conversion structures
(IEEE, 2020)
info:eu-repo/semantics/conferenceObject,
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 ...
Novel three-phase topology for cascaded multilevel medium-voltage conversion systems in large-scale PV plants
(IEEE, 2020)
info:eu-repo/semantics/conferenceObject,
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 ...
On the stability criteria for inverter current control loops with LCL output filters and varying grid impedance
(IEEE, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
The use of LC and LCL filters and grid impedance variations are creating new challenges on the controller design for current control loops of photovoltaic and wind turbine inverters. In the design process, stability criteria ...
The generalized bode criterion: application to the dc voltage control of a three-phase photovoltaic grid-tied inverter
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
As renewable energies are becoming more important in the electrical generation system, power electronic converters are facing new design issues related not only to their components but also to their control loops. In this ...
