Modeling and Control of a Phase-Shifted Full-Bridge Converter for a LiFePO<sub>4</sub> Battery Charger

A proper charge in an electric vehicle (EV) battery allows it to have a longer useful life and lower maintenance costs. For this purpose, the voltage and current supplied to the battery must be precisely regulated. In this article, the model of a phase-shifted full-bridge (PSFB) converter is obtaine...
