Abstract
The usage of a solar-powered buck converter within a low-power Internet of Things (IoT) system is suggested. The goal is to use solar energy to power IoT devices, which often utilize extremely small batteries and need to be aware of their impact on the environment. The system uses PV panels to gather sunlight, which the buck converter then uses to control and enhance the required voltage. Maximum power point tracking (MPPT) and pulse width modulation (PWM) are examples of control strategies used to improve efficiency and provide reliable voltage regulation. By continually modifying the PWM signal's duty cycle in response to the measured output voltage, stable functioning is ensured through feedback control. Reduced use of conventional power sources, longer device life, and the possibility of deployment in locations without access to electrical grids are just a few of the numerous benefits of the proposed system. The PV converter system is implemented in MATLAB software. This idea helps the creation of sustainable and energy-efficient IoT solutions via the use of solar power and advanced control methods.
