Design of an Adaptive Fuzzy Logic Controller for Solar PV Application with High Step-Up DC–DC Converter

In this article, a fuzzy logic controller is developed for the proposed three-phase inverter system to extract the peak power of the solar panel-based generation system. Also, it is useful to maintain the constant grid voltage and frequency. The features of the two-leg three-phase inverter are fast controlling in action, wide-range input, and output operations. A slider controller functionally depended on a small signal model with a low-pass filter is connected to the coupled inductor boost converter (CIBC) to enhance the system dynamic response, infinite switching, and voltage gain at diverse solar irradiation conditions. An adaptive power point tracing controller is applied to the solar photovoltaic (PV)-fed boost converter system to track the peak power of the solar PV.
