An Intelligent IoT-Connected Buck-Boost Converter for Advanced DC Power Management

Abstract

The paper introduces an intelligent Internet of Things (IoT)-connected buck-boost converter that can provide improved direct current (DC) power management. It integrates cloud monitoring, sensing, and control of power flux into a single unit and connects all remote-control nodes through an internet link, which enhances its remote supervision capability. The design looks to fill the practical gap between field-based regulation and supervisory capabilities. The input voltage range for the converter is $24-36 \mathrm{V}$, and it produces a 48 V, 2.5A output. For regulation-inverse operation to fall, the switching frequency should be 20 kHz. A Proportional-Integral-Derivative (PID) controller is introduced to maintain constant output voltage under variable sources and loads with Communication-Aware Sensing, supporting remote data acquisition, including underdamped and signal noise. This mathematical model includes inductor voltage dynamics, capacitor current behavior, ripple estimations, conversion efficiency, and delayed measurement representation for realistic Internet operations. Performance evaluation shows excellent gate generation, controlled inductor current response, and steady output voltage regulation. The results show low voltage ripple (0.15), low current ripple (0.42), and best-case voltage regulation (0.12). Together with all the intelligent monitoring capacity available for DC bus work, these results now demonstrate markedly better electrical behavior. In real applications, the user has developed a configuration that enables regulation, observability, and reliable remote control.
