This report entails the design of a boost converter for a PV array maximum power point tracking (MPPT) system. The system’s main objective is to always extract maximum power from photovoltaic cells. The system uses an incremental conductance MPPT algorithm to track the maximum power of a PV array. A theoretical and literature study that relates to this work was conducted and included in the report. The project feasibility study, and the functional and nonfunctional specifications are listed.
