New silicon thin-film technology associated with original DC–DC converter: An economic alternative way to improve photovoltaic systems efficiencies

Design and experimental implementation of a new robust observer-based nonlinear controller for DC-DC buck converters

“…Influenced by the rapid developments of renewable energy, power electronics, and smart grids, switching DC-DC converters are becoming essential nowadays. For their low cost, high power efficiency and simple structure, their many end-user applications [11] range from fuel and solar cells [12,13], portable electronic devices [14], DC microgrids and motor drives [15], electric and hybrid vehicles [16,17], to photovoltaic systems [18] and wind turbine generators [19]. As mentioned in [11], there are two main control application challenges that must be addressed for the converters to match the source and the load; these energy sources are subject to disturbances and variations due to environmental conditions while each of them has different energy generation characteristics that should be properly addressed.…”
