Résumé / Abstract
This work deals with the study, adaptation and experimental validation of a 9kW lead-acid battery charger used to feed the 72VDC bus inside the hybrid electric locomotive demonstrator in the frame of the French research project PLATHEE. The topology of the charger is based on a high frequency double resonant series-parallel circuit which allows soft switching, losses minimization, reduction of passive component weight and facilitates system integration. Specific charging and floating modes were applied to the battery. The battery charger working has been first validated on a laboratory test-bench using a battery emulator, and then integrated in the locomotive. Simulations have been done, completed with experimental results which are presented in the paper.
