What are the different types of isolated converter topologies for battery charging system and which one is the most efficient now a days. Kindly give answers with valuable references.
Adding to Michalis who gave a short but clear answer you can get more detailed information about the isolated DC to DC battery charger converters by following the thesis:High Efficiency DC-DC Converter for EVBattery Charger Using Hybrid Resonant and PWM Technique in the link:https://theses.lib.vt.edu/theses/available/etd-05072012-141855/unrestricted/Wan_HM_T_2012.pdf
