MATLAB-Based Phase-Shifted Full-Bridge Simulation Research with Constant Current Control

This MATLAB-based phase-shifted full-bridge simulation research with constant current control represents a significant study in power electronics. The research employs MATLAB/Simulink environment to conduct comprehensive simulations of phase-shifted full-bridge converters, specifically investigating their performance characteristics and optimization methods under constant current conditions. The implementation involves developing control algorithms using MATLAB's Power Electronics Toolbox, where key functions like phase-shift modulation and current feedback loops are programmed to maintain constant output current. Through comparative analysis of different simulation scenarios, we have derived important conclusions regarding converter efficiency, transient response, and stability. The simulation model incorporates PID controllers for current regulation and utilizes pulse-width modulation techniques with adjustable phase shifts between bridge legs. Furthermore, the study discusses limitations of the current approach and outlines future research directions, including potential enhancements with advanced control strategies like fuzzy logic or model predictive control. This research holds substantial importance for the development and optimization of power electronic systems, particularly in applications requiring precise current control such as battery charging systems and electric vehicle power converters.
