Pareto-Optimal Design of Litz-Wire Gapped-Core High-Frequency Transformer for LLC Converters

The optimization of Litz-wire gapped-core high-frequency transformer (LGHT) for LLC converters is a challenging task owing to application requirements and complex relationship between multiple design-objectives and constraints. This necessitates the use of multiobjective optimization-techniques to obtain tradeoff design-solutions; however, these are cumbersome methods that require many iter...
