Hybrid-Switching Full-Bridge DC–DC Converter With Minimal Voltage Stress of Bridge Rectifier, Reduced Circulating Losses, and Filter Requirement for Electric Vehicle Battery Chargers
TL;DR: In this article, a hybrid-switching phase-shift full-bridge dc-dc converter is derived for electric vehicle battery chargers, which provides wide zero-voltage switching range in the leading leg switches, achieves zero-current switching for lagging-leg switches, and uses a hybrid switching method to avoid freewheeling circulating losses in the primary side.
