Abstract


In the article the circuit design solution of DC-DC regulated resonant converter has been proposed for using with hybrid photovoltaic modules equipped with a cooling system and solar concentrators to ensure maximum electric power during the module operation. The using of computer simulation and algorithm with numerous iterations greatly facilitates the determining of the resonance circuit optimal parameters for use in DC–DC converters with a wide range of input and output performance. Based on calculated optimal parameters of the resonance LLC circuit it can be show high values of electrical energy transformation efficiency for photovoltaic energy station equipped with high efficiency hybrid photovoltaic modules.  Implementation of digital control into DC–DC converter design opens up wide opportunities for creating control algorithms that ensure the reliability and conversion efficiency, rapid and accurate maximum power point finding, creating information network for monitoring parameters of photovoltaic modules converters itself and the whole photovoltaic station.
