      Capítol de llibre
      Accés restringit per política de l'editorial
      This chapter redefines silicon-based solar cells by introducing the concept of charge-carrier selective contacts. In this sense, heterojunction solar cells use crystalline silicon as a high-quality light absorber. Then, ...

    • Chapter 4: intelligent fault diagnosis of photovoltaic systems 

      Chouder, Aissa; Silvestre Bergés, Santiago (2022-07-13)
      Capítol de llibre
      Accés restringit per política de l'editorial
      Photovoltaic (PV) systems operating in real conditions of work are very often subject to several faults that may lower significantly the produced energy and shorten their availability. Therefore, powerful and trusted fault ...

    • Effects of stray capacitance to ground in impedance measurements 

      Aliau Bonet, Carles; Quílez Figuerola, Marcos (Elsevier, 2021)
      Capítol de llibre
      Accés restringit per política de l'editorial
      Inductive effects such as positive phase angles in impedance measurements have often confused the researchers when the material measured is nonmagnetic. When the measurement is based on auto-balancing bridge method and the ...

    • Automated chlorine dosage in a simulated drinking water treatment plant: a real case study 

      Gámiz Caro, Javier Francisco; Grau Saldes, Antoni; Martínez García, Herminio; Bolea Monte, Yolanda (Multidisciplinary Digital Publishing Institute (MDPI), 2021-11)
      Capítol de llibre
      Accés obert
      In recent decades, increasing attention has been paid to the sustainability of products and processes, including activities aimed at environmental protection, site reclamation or treatment of contaminated ef¿uents, as well ...

    • The Cuckoo search algorithm applied to fuzzy logic control parameter optimization 

      García Gutiérrez, Gustavo; Arcos Aviles, Diego Gustavo; Carrera, Evaristo Vicente; Guinjoan Gispert, Francisco; Ibarra, Andrés; Ayala Taco, Paul (Springer, 2021-01-01)
      Capítol de llibre
      Accés restringit per política de l'editorial
      In the design of control systems, the tuning of controller parameters has a fundamental role in the performance of both transient and steady-state regimes. From this perspective, the tuning of controller parameters has ...

    • Neutral-point-clamped DC-AC power converters 

      Busquets Monge, Sergio (2018-02-22)
      Capítol de llibre
      Accés obert
      This article reviews the fundamentals of multilevel multiphase neutral-point-clamped DC–AC power converters. These converters are configured with one or more legs and a common DC-link. Each leg is functionally equivalent ...

    • 5GHz CMOS all-pass filter-based true time delay cell 

      Aghazadeh Dafsari, Seyed Rasoul; Martínez García, Herminio; Saberkari, Alireza (Multidisciplinary Digital Publishing Institute (MDPI), 2020)
      Capítol de llibre
      Accés obert
      Analog CMOS time-delay cells realized by passive components, e.g., lumped LC delay lines, are inefficient in terms of area for multi-GHz frequencies. All-pass filters considered as active circuits can, therefore, be the ...
