The design of a LLC resonant converter with high efficiency target (both energetic and economic) should consider the constraints related to the physical parameters of the transformer which is supposed to use.
Thanks to our proprietary software we are able to provide a quick and efficient support, working with electronic designers, in defining the "resonant tank" parameters in order to minimize the losses (including MOSFET's conduction losses) to obtain the best efficiency in each of our formats.
