Phase-Shifted Full Bridge Wireless Power Transfer Model in MATLAB

Wireless power transfer (WPT) is the process of transmitting electrical energy from a power source to an electrical load without physical connections. This technology utilizes electromagnetic induction or microwave transmission principles to transfer energy through air. From an implementation perspective, WPT systems typically involve resonant tank circuits, power electronics converters, and control algorithms. In MATLAB simulations, key components include: - Phase-shifted full-bridge converter modeling using Simulink Power Electronics Library - Resonant frequency tuning with LC component calculations - Closed-loop control system design for efficiency optimization The MATLAB implementation would typically involve: 1. Circuit modeling with semiconductor devices (MOSFETs/IGBTs) and passive components 2. Control algorithm development using PID controllers or phase-shift modulation techniques 3. Efficiency analysis through power loss calculations and thermal modeling This technology has transformative potential for electronic device charging by eliminating cords and cables. Key applications include electric vehicle charging, medical implant powering, and mobile device charging. Researchers continuously work to improve WPT system efficiency and range through advanced control algorithms and resonant circuit optimization, making it a promising field for future energy transmission solutions.
