LLC Resonant Converter based Electric Vehicle Battery charger using LabVIEW

SEEE DIGIBOOK ON ENGINEERING & TECHNOLOGY, VOL. 01, FEB 2018 PP.(105-109)
Abstract– This projects presents a performance analysis of LLC resonant converter based electric vehicle battery charger using LabVIEW. New LLC resonant converter with two transformers in parallel for the electric vehicle battery charger. This topology achieves the zero-voltage switching for main switches in the entire charging profile. In addition, the zero-current switching for output rectifier diodes is extended under charging condition. The proposed charger provides a wide range output voltage for the battery system because charge equalization algorithm used to achieve higher efficiency for battery charging system. Moreover, in order to maintain the high efficiency undercharging, the charger adopts a bidirectional switch. At low-output power condition, the charger uses one transformer to transfer the energy. Finally, the design procedure is provided and implemented in a prototype charger with the input DC link 230 V and the output voltage of 12–24 V. Experimental results are presented to demonstrate the system performance. peak efficiency is as high as 93.6%.
