The use of photoelectric-converter modules (PCM) with integrated direct-current regulators in low- and medium-power-supply systems working jointly with an industrial network permits production to be increased of the power generated by photoelectric-converter modules due to operation of all modules in the maximum power-generation mode. With the decrease in the intensity of solar radiation of some of the chain of the series-connected photoelectric-converter modules, the simultaneous work of all modules of the chain in the maximum power selection mode can lead to the appearance of overvoltages on elements of direct-current regulators integrated into the modules. A means is proposed in this article to control the chain of seriesconnected photoelectric-converter modules with integrated direct-current regulators. The control algorithm of the direct-current regulators permitting one to equalize the voltage at the output of the series-connected regulators under very nonuniform illumination of the photoelectric-converter modules. Computer models are studied, and results of simulation in Matlab/Simulink software system are presented.
