title = "Investigation of design methodology of planar transformers for EV on board chargers",
abstract = "In this paper, a generalized design and optimization methodology is proposed for planar transformers. In stead of applying fancy optimization algorithms which employs numerous free parameters, the proposed methodology utilizes very few geometry-related free variables. As a result, it is easy to find patterns and trade-offs during the optimization process. Followed the proposed methodology, a planar transformer prototype is designed for a 6.6 kW/500 kHz CLLC resonant converter. The CLLC resonant converter serves as the isolated dc/dc stage for EV on board chargers. The CLLC converter is tested at full load condition and the transformer exhibits more than 99.4% efficiency.",
