Analytical Design Methodology for Litz-Wired High-Frequency Power Transformers PROJECT TITLE :Analytical Design Methodology for Litz-Wired High-Frequency Power TransformersABSTRACT:Within the last quarter of a century, high-frequency (HF) transformer design has been one in every of the main issues to Power Electronics designers so as to increase converter power densities and efficiencies. Typical design methodologies are primarily based on iterative processes and rules of thumb founded additional on experience than on theoretical developments. This paper presents an analytical design methodology for litz-wired HF power transformers that gives a deep insight into the transformer design drawback creating it a robust tool for converter designers. The most suitable models for the calculation of core and winding losses and the transformer thermal resistance are 1st selected and then validated with a 5-kW fifty-kHz business transformer for a photovoltaic application. Primarily based on these models, the look methodology is finally proposed, reducing the design issue to directly solve a 5-variable nonlinear optimization problem. The methodology is illustrated with a detailed design in terms of magnetic material, core geometry, and first and secondary litz-wire sizing. The optimal style achieves a 46.fivep.c power density increase and a higher efficiency of 99.seventypercent in comparison with the commercial one. Did you like this research project?
