Summary:The invention relates to an extremal electronic regulator to be used to control the operation of photovoltaic panels at the point of maximum power, in order to provide them a high efficiency in operation. According to the invention, the regulator comprises a generator (1) which generates a triangle disturbance signal the application of which is controlled by an electronic power converter (7), simultaneously with two short pulses, synchronized with the triangle signal, the disturbance effects being detected by a power transducer (9) whose output signal is memorized in two circuits (2, 3), a sampling and a retaining circuit, in successive alternating moments, controlled by the pulses of the generator (1), and the signal resulting by the decrease of the signals memorized in the sampling and retaining circuits (2, 3) is applied to a usual integrator regulator (4) in order for it to produce an intermediate control signal which will be added to the triangle signal, to result in the control signal for the electronic converter (7) which will thus ensure the operation of the photovoltaic panel in the point of maximum power. Invenţia se referă la un regulator extremal electronic utilizat la controlul funcţionării panourilor fotovoltaice în punctul de putere maximă, pentru a le asigura acestora o eficienţă ridicată în funcţionare. Regulatorul conform invenţiei cuprinde un generator (1) care produce un semnal de perturbaţie triunghiular care este aplicat la comanda unui convertor (7) electronic de putere, concomitent cu două impulsuri scurte, sincronizate cu semnalul triunghiular, efectele perturbaţiei fiind sesizate cu ajutorul unui traductor (9) de putere a cărui semnal de ieşire este memorat în două circuite (2, 3) de eşantionare şi reţinere, în momente succesive alternative, comandate de impulsurile generatorului (1), iar semnalul rezultat prin scăderea semnalelor memorate în circuitele (2, 3) de eşantionare şi reţinere este aplicat unui regulator (4) integrator uzual pentru a produce un semnal intermediar de control care se va însuma cu semnalul triunghiular, obţinându-se astfel semnalul de comandă pentru convertorul (7) electronic ce va asigura, în acest mod, funcţionarea panoului fotovoltaic în punctul de putere maximă.
