A comparison of techniques for fault detection in inverter-fed induction motors in transient regime

Fernandez-Cavero, Vanessa; Morinigo-Sotelo, Daniel; Duque-Perez, Oscar; Pons Llinares, Joan (Institute of Electrical and Electronics Engineers, 2017)

[EN] Fault detection in induction motors operating in non-stationary regimes has become a need in today's industry. Most of the works published deal with line-fed motors. Nevertheless, the number of inverterfed induction ...
An Adaptive Digital Control Technique for Improved Performance of Grid Connected Inverters

González Espín, Francisco José; Patrao Herrero, Iván; Figueres Amorós, Emilio; Gabriel Garcerá (Institute of Electrical and Electronics Engineers (IEEE), 2013)

Grid connected voltage source inverters may be controlled in the stationary reference frame by means of the infinite impulse response (IIR) P+Resonat regulator. This regulator is able to correctly track fixed frequency ...

[ES] A lo largo de este proyecto se realiza el diseño completo de una instalación solar fotovoltaica de 20 MW de corriente alterna situada cerca del río Khan en Ebony, perteneciente a la región de Erongo en Namibia. En ...
Dynamic modeling of DC-DC converters with peak current control in double-stage photovoltaic grid-connected inverters

Garcerá Sanfeliú, Gabriel; González Medina, Raúl; Figueres Amorós, Emilio; Sandía Paredes, Jesús (Wiley, 2012-08)

In photovoltaic (PV) double-stage grid-connected inverters a high-frequency DC-DC isolation and voltage step-up stage is commonly used between the panel and the grid-connected inverter. This paper is focused on the modeling ...
Optimización de Funciones de Coste para Control Predictivo de Máquinas de Inducción Multifásicas

Arahal, Manuel R.; Kowal G., Agnieszka; Barrerro, Federico; Castilla, María del Mar (Universitat Politècnica de València, 2018-12-13)

[EN] Control of multi-phase induction machines is evolving with the incorporation of predictive controllers that operate directly with the power converter without modulators. It is realized in discrete-time through an ...
