A low-cost photovoltaic emulator for static and dynamic evaluation of photovoltaic power converters and facilities

González Medina, Raúl; Patrao Herrero, Iván; Garcerá Sanfeliú, Gabriel; Figueres Amorós, Emilio (Wiley, 2014-02)

In testing maximum power point tracking (MPPT) algorithms running on electronic power converters for photovoltaic (PV) applications, either a PV energy source (PV module or PV array) or a PV emulator is required. With a ...
An adaptive synchronous-reference-frame phase-locked loop for power quality improvement in a polluted utility grid

González Espín, Francisco José; Figueres Amorós, Emilio; Garcerá Sanfeliú, Gabriel (Institute of Electrical and Electronics Engineers (IEEE), 2012-06)

The proper operation of grid-connected power electronics converters needs using a synchronization technique to estimate the phase of the grid voltage. The performance of this synchronization technique is related to the ...
Comparative study of speed estimators with highly noisymeasurement signals for Wind Energy Generation Systems

Carranza Castillo, Oscar; Figueres Amorós, Emilio; Garcerá Sanfeliú, Gabriel; González Morales, Luis Gerardo (Elsevier, 2011-03)

This paper presents a comparative study of several speed estimators to implement a sensorless speed control loop in Wind Energy Generation Systems driven by power factor correction three-phase boost rectifiers. This rectifier ...
Control techniques for reduction of the total harmonic distortion in voltage applied to a single-phase inverter with nonlinear loads: Review

Ortega, Rubén; Figueres Amorós, Emilio; Garcerá Sanfeliú, Gabriel; Trujillo Rodríguez, César Leonardo; Velasco de la Fuente, David (Elsevier, 2012-04)

[EN] This paper presents the design, analysis and implementation of four control techniques (proportional-integral, two-degree of freedom, repetitive and resonant) with the aim of reducing the total harmonic distortion in ...
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 ...
Low power wind energy conversion system based on variable speed permanent magnet synchronous generators

Carranza Castillo, Oscar; Garcerá Sanfeliú, Gabriel; Figueres Amorós, Emilio; González Morales, Luis Gerardo (Wiley, 2014-06)

This paper presents a low power wind energy conversion system (WECS) based on a permanent magnet synchronous generator and a high power factor (PF) rectifier. To achieve a high PF at the generator side, a power processing ...
Transformerless topologies for grid-connected single-phase photovoltaic inverters

Patrao Herrero, Iván; Figueres Amorós, Emilio; González Espín, Francisco José; Garcerá Sanfeliú, Gabriel (Elsevier, 2011-09)

[EN] In order to improve the efficiency and reduce the cost of a photovoltaic system, the use of transformerless photovoltaic inverters is an alternative of increasing interest. However, this topology needs to be studied ...
