Eee Projects On Solar Mobile Charger With 5V Usb Output: Power Electronics, MATLAB/Simulink & Circuit Modeling Integrated Analysis: MATLAB/Simulink · MOSFET/IGBT Gate Drivers · SPWM/SVPWM · THD Spectrum · ~6749 Words Chapter 1: Power Electronics Overview, System Specifications & Topology Modeling This project presents the design and implementation of a solar-powered cellphone charger capable of delivering a regulated 5V, 2A output for charging mobile devices directly from solar energy.

Analytical & State-Space Control Methodology

The system was developed as a Final Year Project in Electrical and Electronic Engineering with the objective of providing a reliable, portable, and environmentally friendly charging solution using renewable energy. The design focuses on efficient voltage conversion, output stability, component protection, and practical implementation using readily available electronic components.

Simulink Waveforms & Power Quality Findings

A solar panel converts sunlight into electrical energy and serves as the primary power source for the charger. The protection stage prevents reverse current flow and protects sensitive components from electrical damage. The LM2596 switching regulator reduces the solar panel voltage to a stable 5V output suitable for mobile device charging.
