Abstract

The use of modern hardware and software design allows to effectively solve a number of problems associated with the development of various technical devices. The specificity of this approach is the development of algorithms with the capabilities of dynamic correction of the design process with the participation of the user. The algorithm of the software implementation of designing protection circuits against electrical overloads in photovoltaic modules of solar arrays using a voltage limiting device based on metal oxide varistor and posistor of the PolySwitch type being in thermal contact is described in this paper. The algorithm provides for determining the optimal technical parameters of the voltage limiting device (minimum resistance and tripping current of the posistor element, classification voltage and non-linearity coefficient of the varistor element) for the operation of photovoltaic module, which is in the state of lighting in the absence and presence of faulty, degraded, or shaded photovoltaic cells.
