Abstract:
This paper is focused on the design and development of a new DC/DC converter based on LLC topology for charging the traction battery in an electric vehicle from the fuel cell stack. The input voltage range is 16-22 V and the output voltage is 275-350 V operating at maximum power of 1.25 kW (5 kW, four in parallel). The presented demonstrator consists of four parallel converters. The DC/DC converter has a high efficiency of about 95 %, high power density and low cost.
