Design and Implementation of an IoT-Enabled Buck-Boost Converter for Adaptive Solar Energy Regulation

The lack of solar photovoltaic (PV) output stability caused by irradiance and temperature makes maintaining a constant DC supply of battery-based energy storage systems challenging. This paper will comment on the design and development of an IoT-enabled buck-boost converter with adjusting PV output control to offer reliable and efficient charging in diverse environmental conditions. In the proposed system, an ESP32 microcontroller is used to dynamically adjust converter duty cycle with PWM depending on real-time voltage and current measurements. The two-mode power control system is an automatic system, which turns over to two modes between buck and boost system at the changes in solar panel voltage and battery charging requirements. In sunny, cloudy and dismal conditions a 2 W and 10…
