This paper presents the development of a photovoltaic (PV)-powered DC-DC boost converter system, optimized for battery charging applications. This system addresses the challenge of input voltage variability, which is a common issue when using PV modules as the power source. Due to fluctuations in solar irradiance, the output voltage from the PV module can vary, affecting the charging process. To ensure a stable and constant output voltage for battery charging, the system integrates a DC-DC boost converter governed by a Proportional-Integral-Derivative (PID) controller. The design specifically targets a 35V 21Ah lead-acid battery, with the converter adjusting the PV module's input voltage of 32.64V to a steady output voltage of 41.15V. The successful implementation of the PID controller mitigates voltage oscillations, maintaining the output voltage at a desired level, thereby optimizing the battery charging process and enhancing system efficiency.
