  • Chapter 4: intelligent fault diagnosis of photovoltaic systems 

    Chouder, Aissa; Silvestre Bergés, Santiago (2022-07-13)
    Part of book or chapter of book
    Restricted access - publisher's policy
    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)
    Part of book or chapter of book
    Restricted access - publisher's policy
    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 ...

    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)
    Part of book or chapter of book
    Open Access
    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)
    Part of book or chapter of book
    Open Access
    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 ...

    Linear-assisted DC/DC regulators (or linear-switching hybrid DC/DC regulators) consist of a linear voltage regulator (classic NPN/nMOS topologies or PNP/pMOS low-dropout structures) connected in parallel with a switching ...
  • Low drop-out voltage regulator as a candidate topology for photovoltaic solar facilities 

    Martínez García, Herminio; García Vílchez, Encarnación (Cambridge Scholars Publishing, 2020)
    Part of book or chapter of book
    Open Access
    This chapter presents a design for a 4.5-V, 450-mA low drop-out (LDO) linear voltage regulator based on a two-stage cascode operational transconductance amplifier (OTA) as an error amplifier for photovoltaic solar DC-DC ...
