Power Control of Solar Cell Voltage by Using DC-DC Boost Converter

Solar power generation systems typically consist of a solar array and a DC-DC converter. The DC-DC converter is a device that converts the direct current (DC) output from the (PV) panel into a different DC voltage level, such as a DC-DC boost converter. This research aims to develop the DC-DC boost converter with the inverter to increase the voltage supply to the electrical grid. DC-DC boost converter with inverter was simulated using Simulink MATLAB. The analysis of the output DC voltage, current, and power was performed. Then, the analysis of the steady output current and PV solar voltage depending on solar irradiation as input at the PV panel was analyzed. The result shows that when the solar irradiation on the PV panel increased, then the output voltage and current of the PV panel would also increase. This study also involves the small signal analysis of the boost converter, which is highly useful for stability analysis. Thus, a DC-DC boost converter with solar irradiation as the input to the electrical grid would increase the voltage of the direct current generated by a photovoltaic and stabilize the output voltage control by a maximum power point tracker (MPPT).
